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

Namespaced the generated headers with `zephyr` to prevent

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
generate a build-time warning message, similar to the
`CONFIG_TIMER_RANDOM_GENERATOR`.

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.

Currently, all devices are initialized at boot time (following their
level and priority order). This patch introduces deferred
initialization: by setting the property `zephyr,deferred-init` on a
device on the devicetree, Zephyr will not initialized the device.
To initialize such devices, one has to call `device_init()`.
Deferred initialization is done by grouping all deferred devices on a
different ELF section. In this way, there's no need to consume more
memory to keep track of deferred devices. When `device_init()` is
called, Zephyr will scan the deferred devices section and call the
initialization function for the matching device. As this scanning is
done only during deferred device initialization, its cost should be
bearable.

NUS is implemented as a Bluetooth LE service, exchanging data treating
the NUS characteristics as Serial endpoints: RX characteristic to
receive, TX characteristic to send binary packets.
This implementation also enables the ability to define multiple
instances of the NUS Service, analogous to mutliple serial endpoints,
to use each one for different purposes. Unless disabled through Kconfig,
NUS instantiates a default instance, similar to what other services do,
which allows users not interested in using multiple instances, to not
worry about the inherent complexities.

Currently, the z_shared_isr symbol is only kept if
CONFIG_DYNAMIC_INTERRUPTS=n. Whenever CONFG_DYNAMIC_INTERRUPTS
is set to 'y', said symbol gets dropped when zephyr_pre0.elf
is created. This is wrong because dropping/keeping z_shared_isr
shouldn't be influenced by enabling/disabling support for the
dynamic interrupts.

dependency on CONFIG_DYNAMIC_INTERRUPTS.

The linker was optimizing away z_shared_isr() the zephyr_pre0.elf image
since the function is not used. However, zephyr.elf does use this
function via isr_tables.c file, generated after zephyr_pre0.elf.
This difference caused a shift in all symbol addresses by the size of the
z_shared_isr() function. isr_tables.c had pointers for zephyr_pre0.elf.
The build system assumes the ISR addresses are the same between both .elf
files, when in fact, before this fix, they were not.
When run on a device, interrupts were calling non-interrupt functions.

This commit introduces all the necessary changes for
enabling the usage of shared interrupts.
This works by using a second interrupt table: _shared_sw_isr_table
which keeps track of all of the ISR/arg pairs sharing the same
interrupt line. Whenever a second ISR/arg pair is registered
on the same interrupt line using IRQ_CONNECT(), the entry in
_sw_isr_table will be overwriten by a
(shared_isr, _shared_sw_isr_table[irq]) pair. In turn, shared_isr()
will invoke all of the ISR/arg pairs registered on the same
interrupt line.
This feature only works statically, meaning you can only make use
of shared interrupts using IRQ_CONNECT(). Attempting to dynamically
register a ISR/arg pair will overwrite the hijacked _sw_isr_table
entry.

ZBus stores observers in two ways: statically using a list and dynamically
using a memory slab. Both present limitations. Static observers work only
for channel definition. The dynamic observers rely on a memory slab that
forces the user to manage its size to avoid issues with adding
observers. This commit fixes the static allocation problem by using the
iterable sections for allocating observation data and replacing the VDED
execution sequence since now it is possible to prioritize static observer
execution. All the runtime observers are dynamically allocated on the heap
instead of a specific memory pool.
BREAK changes (only internal, not APIs):
* ZBus channel metadata changed. Remove the observers' static array
pointer. Rename the `runtime_observers` pointer to `observers`. Add
`observer_start_idx` and `observer_end_idx`;
* Change the VDED execution sequence. The position (on definition time),
the priority in conjunction with the lexical order, is considered for
static post-definition time observers. At last, the runtime observer
follows the adding sequence;
* Replace the `CONFIG_ZBUS_RUNTIME_OBSERVERS_POOL_SIZE` with
`CONFIG_ZBUS_RUNTIME_OBSERVERS`.
New APIs:
* New iterable section iterators (for channels and observers) can now
receive a user_data pointer to keep context between the function calls;
* New `ZBUS_LISTENER_DEFINE_WITH_ENABLE(_name, _cb, _enable)` and
`ZBUS_SUBSCRIBER_DEFINE_WITH_ENABLE(_name, _queue_size, enable)` that
enable developers define disabled observers. They need to be enabled
during runtime to receive notifications from the bus;
* `ZBUS_CHAN_ADD_OBS` macro for adding post-definition static observers of
a channel.
Important changes:
* Move the ZBus LD file content to the `common-ram.ld` LD file. That was
necessary to make ZBus compatible with some Xtensa and RISCV boards.
