This commit introduces support for an alternate linking method in the
LLEXT subsystem, called "SLID" (short for Symbol Link Identifier),
enabled by the CONFIG_LLEXT_EXPORT_BUILTINS_BY_SLID Kconfig option.
SLID-based linking uses a unique identifier (integer) to identify
exported symbols, instead of using the symbol name as done currently.
This approach provides several benefits:
* linking is faster because the comparison operation to determine
whether we found the correct symbol in the export table is now an
integer compare, instead of a string compare
* binary size is reduced as symbol names can be dropped from the binary
* confidentiality is improved as a side-effect, as symbol names are no
longer present in the binary

using CMAKE_CURRENT_LIST_DIR.

Introduce a temporary Kconfig `LEGACY_GENERATED_INCLUDE_PATH`

continue the use of the old include paths for the time being
until it is deprecated and eventually removed. The Kconfig will

Previously the multi-level irq lookup table is generated by
looping through the devicetree nodes using macros & Kconfig,
which is hard to read and flimsy.
This PR shifts the heavy lifting to devicetree & DT macros such
that an interrupt controller driver, which has its info in the
devicetree, can register itself directly with the multi-level
interrupt architecture, which is more straightforward.
The previous auto-generated look up table with macros is now
moved in a file of its own. A new compatibility Kconfig:
`CONFIG_LEGACY_MULTI_LEVEL_TABLE_GENERATION` is added and
enabled by default to compile the legacy look up table for
interrupt controller drivers that aren't updated to support the
new architecture yet.

Some tool like NixOS / Nix package manager sets this variable

A new Kconfig option which generates syscall stubs assuming that
extensions will always run on userspace, thus simplifying linking
them, as there's no need for z_impl_ stubs (used for direct syscalls),
CONFIG_LLEXT_EDK_USERSPACE_ONLY.
While defining __ZEPHYR_USER__ could have the same effect for optmised
builds, people building extensions on debug environments - thus
non-optimised - would suffer, as they'd need to somehow make the stubs
available (by either exporting the symbol or implementing dummy stubs).

Loadable extensions need access to Zephyr (and Zephyr application)
includes and some CFLAGS to be properly built. This patch adds a new
target, `llext-edk`, which generates a tar file with those includes and
flags that can be loaded from cmake and make files.
A Zephyr application willing to expose some API to extensions it loads
only need to add the include directories describing such APIs to the
Zephyr ones via zephyr_include_directories() CMake call.
A new Kconfig option, CONFIG_LLEXT_EDK_NAME allows one to control some
aspects of the generated file, which enables some customization - think
of an application called ACME, willing to have a ACME_EXTENSION_KIT or
something.
All EDK Kconfig options are behind CONFIG_LLEXT_EDK, which doesn't
depend on LLEXT directly - so that EDK features can be leveraged by
downstream variations of loadable extensions.
Also, each arch may need different compiler flags for extensions: those
are handled by the `LLEXT_CFLAGS` cmake flag. An example is set for GCC
ARM.
Finally, EDK throughout this patch means Extension Development Kit,
which is a bad name, but at least doesn't conflict with SDK.

Change the GCC toolchain configuration to make use of the Cortex-R82
target. When Cortex-R82 was added as a GCC toolchain option, the GCC
version of the Zephyr SDK did not support Cortex-R82 tuning. Zephyr was
therefore compiled compiled for the Armv8.4-A architecture. Since Zephyr
SDK 0.15.0 (which updated GCC from 10.3.0 to 12.1.0) coupled with Zephyr
3.2, the Cortex-R82 target is supported.
The Armv8-R AArch64 architecture does not support the EL3 exception level.
EL3 support is therefore made conditional on Armv8-R vs Armv8-A.

On very early stage build system needs to get access to DTC preprocessor.
MWDT has no it's own preprocessor, so here zephyr-SDK preprocessor is used.
On latest build stages zephyr-SDK objcoby also required as MWDT binutils
don't support all features. This at the same time requires that
ZEPHYR_SDK_INSTALL_DIR must be initialized with valid arch-dependent
prefix.
Zephyr-SDK requires ARCH variable to be initialized before
include "generic.cmake", but in hew HWMv2 model ARCH variable will be
initialized more later. This workaround uses any (first awailable,
independent on ARCH) toolchain from SDK for DTC preprocessing only.
For other build stages ARCMWDT will be used.

Currently, clang produces a warning that the '--specs=nosys.specs' argument
is unused. Remove this flag to fix the warning as clang will generally not
honor '--specs' when targeting arm baremetal.
While this flag has been present for some time, I think this should be safe
to do. For background, clang does not seem to handle '--specs' [1] besides
possibly passing it through to GCC if GCC is used as the driver for
linking. However, whether GCC will be used for linking as a fallback
depends on the "Toolchain" [1] clang uses internally, which in turn depends
on the triple. For arm/thumb baremetal triples, the Toolchain clang uses
will not fall back to GCC to drive linking, so '--specs' will never be used
here.
I believe this behavior in clang is fairly longstanding as well (since
~2017/LLVM 5 [2]). While there isn't a minimum required clang version for
Zephyr, Zephyr currently requires lld >= 14.0.0. So, I don't think removing
this flag should impact current users (besides preventing the warning).

This adds supports for flashing images with sysbuild where there
are multiple images per board to prevent using the same command per
image flash which might cause issues if they are not ran just once
per flash per unique board name. A deferred reset feature is also
introduced that prevents a board (or multiple) from being reset if
multiple images are to be flashed until the final one has been
flashed which prevents issues with e.g. security bits being enabled
that then prevent flashing further images.
These options can be set at a board level (in board.yml) or a SoC
level (in soc.yml), if both are present then the board configuration
will be used instead of the SoC, and regex can be used for matching
of partial names which allows for matching specific SoCs or CPU cores
regardless of the board being used

This commit reverts a breaking change in CMAKE_SYSTEM_NAME introduced by
"Zephyr" back to "Generic") and removes the file
`cmake/modules/Platform/Zephyr`.
Both changes in the aforementioned PR were only introduced to ultimately
modify the value of the global CMake property TARGET_SUPPORTS_SHARED_LIBS
for the special case of building for Xtensa with LLEXT.
The modification of CMAKE_SYSTEM_NAME is considered a breaking change
because it has the potential to alter the build of any non-trivial project
that previously checked for the "Generic" system identifier as
corresponding to Zephyr - for example by doing
`if (CMAKE_SYSTEM_NAME STREQUAL "Generic")`. Such builds may now break in
many ways including silently when there is no `else()` clause with a
`message()` to alert the user that a whole configuration block had been
skipped.
In essence, that CMAKE_SYSTEM_NAME modification was only introduced in
order to have CMake to load `cmake/modules/Platform/Zephyr.cmake` which in
turn adjusted the value of TARGET_SUPPORTS_SHARED_LIBS.
But the use of a CMake platform file like this is ineffective for
non-trivial projects where one or more top level CMake `project()` calls
may happen before the first call to `find_package(Zephyr)` because in such
cases CMAKE_MODULE_PATH will not have been modified yet to contain the
path to <Zephyr_ROOT>/cmake/modules and thus no platform file will be
include by CMake.
This patch moves the conditional override of TARGET_SUPPORTS_SHARED_LIBS
needed by some archs (e.g. Xtensa) into the `kernel.cmake` module which
is known to be the first call to `project()` that enables any language and
thus the one that must come before any artifact target can be defined.
Note commit 64e7d85 added a Kconfig to specify the object type of llext
being built, so it's not tied to the arch anymore but to the
CONFIG_LLEXT_TYPE_ELF_SHAREDLIB option.

USB High-Speed devices must be able to operate at both High-Speed and
Full-Speed. The USB specification allows the device to have different
configurations depending on connection speed. Modify the API to reflect
USB Specification requirements on what can (e.g. configurations) and
what cannot (e.g. VID, PID) be speed dependent.
While the class configurations for different speeds are completely
independent, the actual class instances are shared between operating
speeds (because only one speed can be active at a time). Classes are
free to provide different number of interfaces and/or endpoints for
different speeds. The endpoints are assigned for all operating speeds
during initialization.
