This commit allows a more dynamic approach for specifying that a zephyr
library must be placed in a dedicated app memomory partition.
This is still done by defining the partition in code using
K_APPMEM_PARTITION_DEFINE, but now the zephyr library can be added to
the generation of partition table using zephyr_library_app_memory
instead of modifying the overall zephyr/CMakeLists.txt file.

Settings documentation was placed under storage paragraph
in documentation tree, which suggested that it was another
storage solution. In fact settings uses storage modules as
its persistent storage back-end.
This patch creates dedicated run-time configuration paragraph
which aim to explain existence (and emphasize) of common run-time
configuration system in Zephyr-RTOS and rationale for using it.
The Settings paragraph is placed under this paragraph as it is only
sub-module which implements the solution.

This generic video API can be used to capture/output video frames.
Once a video buffer is enqueued to a video device endpoint, device owns
the buffer and can process to capture (camera), output (disk, display),
convert (hw encoder)... User can then call dequeue to retrieve
the processed buffer (video driver ensure cache coherency).
Once dequeued, video buffer is owned by user (e.g. for frame
processing, display buffer update, write to media, etc...).
For each video-buffer, user needs allocate the associated frame buffer
via video_buffer_alloc. Buffer format is defined by video device
endpoint configuration. Video device can be controlled (e.g. contrast,
brightness, flip...) via controls.

System call arguments, at the arch layer, are single words. So
passing wider values requires splitting them into two registers at
call time. This gets even more complicated for values (e.g
k_timeout_t) that may have different sizes depending on configuration.
This patch adds a feature to gen_syscalls.py to detect functions with
wide arguments and automatically generates code to split/unsplit them.
Unfortunately the current scheme of Z_SYSCALL_DECLARE_* macros won't
work with functions like this, because for N arguments (our current
maximum N is 10) there are 2^N possible configurations of argument
widths. So this generates the complete functions for each handler and
wrapper, effectively doing in python what was originally done in the
preprocessor.
Another complexity is that traditional the z_hdlr_*() function for a
system call has taken the raw list of word arguments, which does not
work when some of those arguments must be 64 bit types. So instead of
using a single Z_SYSCALL_HANDLER macro, this splits the job of
z_hdlr_*() into two steps: An automatically-generated unmarshalling
function, z_mrsh_*(), which then calls a user-supplied verification
function z_vrfy_*(). The verification function is typesafe, and is a
simple C function with exactly the same argument and return signature
as the syscall impl function. It is also not responsible for
validating the pointers to the extra parameter array or a wide return
value, that code gets automatically generated.
This commit includes new vrfy/msrh handling for all syscalls invoked
during CI runs. Future commits will port the less testable code.
