Promote the private z_arch_* namespace, which specifies
the interface between the core kernel and the
architecture code, to a new top-level namespace named
arch_*.
This allows our documentation generation to create
online documentation for this set of interfaces,
and this set of interfaces is worth treating in a
more formal way anyway.

Use this short header style in all Kconfig files:
# <description>
# <copyright>
# <license>
...
Also change all <description>s from
# Kconfig[.extension] - Foo-related options
to just
# Foo-related options
It's clear enough that it's about Kconfig.
The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

- Add WDT(0,1) to esp32.dtsi
- Extend the module to be able to use WDT(0,1)
- Some minor refactoring due to usage of device tree
Tests:
- samples/drivers/watchdog
- tests/drivers/watchdog/wdt_basic_api
Note:
- timer module interrupt registers shall be removed when
timer driver implemented.

Move _LINKER and _ASMLANGUAGE to target.cmake because of how we pick the
linker script that might be used. This way regardless of how or where a
linker.ld gets included we will always set _LINKER & _ASMLANGUAGE (so
any header that needs check based on those defines they can,
specifically generated_dts_board.h)

Same deal as in commit 7fdb525754 ("kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), but I hacked Kconfiglib to also
find cases where the type is given separately as e.g.
config FOO
int
default 3
Motivation (from a note in
https://docs.zephyrproject.org/latest/guides/kconfig/index.html):
For a symbol defined in multiple locations (e.g., in a
Kconfig.defconfig file in Zephyr), it is best to only give the
symbol type for the "base" definition of the symbol, and to use
'default' (instead of 'def_<type>' value) for the remaining
definitions. That way, if the base definition of the symbol is
removed, the symbol ends up without a type, which generates a
warning that points to the other definitions. That makes the extra
definitions easier to discover and remove.
It's also nice if 'def_bool' and the like turn into a semi-reliable flag
that the symbol is only defined in Kconfig.defconfig files. That might
be a sign that things could be cleaned up.
Will do a separate pass later to remove some symbols only defined in
Kconfig.defconfig files.

We re-wrote the xtensa arch code, but never got around
to purging the old implementation.
Removed those boards which hadn't been moved to the new
arch code. These were all xt-sim simulator targets and not
real hardware.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.
As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.
The final work to remove this (and overhaul stack specification in
general) will take place in 1.15 in the context of #14269Fixes: #14766

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c
include/linker/kobject-text.ld
kernel/include/syscall_handler.h
scripts/gen_kobject_list.py
scripts/gen_syscall_header.py

The firmware starts us with an already-initialized UART and a simple
ROM hook. Use that as the default printk handler so we can log in
very early boot. It will be overriden later (as it happens, by
another handler based on the same firmware hooks).

This can help find unused symbols. Those end up without a type if
'default' is used instead of 'def_bool', which generates a warning.
Search for "Kconfig.defconfig" in
https://docs.zephyrproject.org/latest/application/kconfig-tips.html for
a longer explanation.
Keep the 'def_bool' for the following symbols, which seem to be
deliberately defined only in Kconfig.defconfig files:
- ALTERA_AVALON_I2C
- ALTERA_AVALON_MSGDMA
- ALTERA_AVALON_PIO
- ALTERA_AVALON_QSPI
- ALTERA_AVALON_SYSID
- CLOCK_CONTROL_IMX_CCM
- CPU_EM4_DMIPS
- CPU_EM4_FPUDA
- CPU_EM4_FPUS
- FP_FPU_DA
- I2C_GECKO

We now place the linker directives for the SW ISR table
in the common linker scripts, instead of repeating it
everywhere.
The table will be placed in RAM if dynamic interrupts are
enabled.
A dedicated section is used, as this data must not move
