Fixes: #23449
This commit adds additional OUTPUT and BYPRODUCTS to custom command
and targets in the Zephyr build system.
This ensures that files produced during the build will be removed again
when invoking ninja clean / make clean.
The generated syscalls headers include folder is added to the syscall
target using ADDITIONAL_CLEAN_FILES property.
However, this property is new in CMake 3.15, so will not work when using
older CMake with ninja.
For CMake versions <=3.15 the ADDITIONAL_MAKE_CLEAN_FILES property is
used. However, this only supports Makefile generator.

With the introduction of ZephyrConfig.cmake all parts of CMake code
should rely on the CMake ZEPHYR_BASE variable instead of the environment
setting.
This ensures that after the first CMake invocation, then all subsequent
invocation in same build folder will use same zephyr base.

Actual files make terrible dependency targets in CMake.
Wrap the generation of subsystems.json into a custom
target to get around this. Fixes a problem where
parse_syscalls.py was being called multiple times.

This change extends the parse_syscalls.py script to scan for a
__subsystem sentinal added to driver api declarations. It thens
generates a list that is passed into gen_kobject_list.py to extend
the subsystems list. This allows subsystems to be declared in the
code instead of a separate python list and provides a mechanism for
defining out-of-tree subsystems.

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.

There is an effort underway to make most of the Zephyr build script's
reentrant. Meaning, the build scripts can be executed multiple times
during the same CMake invocation.
Reentrancy enables several use-cases, the motivating one is the
ability to build several Zephyr executables, or images, for instance a
bootloader and an application.
For build scripts to be reentrant they cannot be directly referencing
global variables, like target names, but must instead reference
variables, which can vary from entry to entry.
Therefore, in this patch, we replace global targets with variables.

This used to be done by hand but can easily be generated like
we do other switch statements based on object type.

Adding a new kernel object type or driver subsystem requires changes
in various different places. This patch makes it easier to create
those devices by generating as much as possible in compile time.
No behavior change.
