PANIC never returns and abort is called to exit the process after calling assert
When BOARD_RESET_ON_ASSERT < 2, the second kasan_report will not be executed.

When size is less than or equal to KASAN_SHADOW_SCALE, no check will be performed
We need to check whether the memory is accessible based on bit

In function kasan_set_poison:
{
...
while (size--)
{
p[size] = value;
}
}
This will optimize to 'memset' function when compile option > O2.
But the memset must be instrument by kasan, so there is recursive

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

This enables CMake based build for sim:ostest. Flags which
are set by set_source_files_properties are not reflected in
final build. Changing these to target_compile_options makes
CMake build runnable.

Extracting global variable information using scripts:
kasan_global.py:
1. Extract the global variable information provided by the -- param asan globals=1 option
2. Generate shadow regions for global variable out of bounds detection
Makefile:
1. Implement multiple links, embed the shadow area into the program, and call it by the Kasan module

1. Update all CMakeLists.txt to adapt to new layout
2. Fix cmake build break
3. Update all new file license
4. Fully compatible with current compilation environment(use configure.sh or cmake as you choose)
------------------
How to test
From within nuttx/. Configure:
cmake -B build -DBOARD_CONFIG=sim/nsh -GNinja
cmake -B build -DBOARD_CONFIG=sim:nsh -GNinja
cmake -B build -DBOARD_CONFIG=sabre-6quad/smp -GNinja
cmake -B build -DBOARD_CONFIG=lm3s6965-ek/qemu-flat -GNinja
(or full path in custom board) :
cmake -B build -DBOARD_CONFIG=$PWD/boards/sim/sim/sim/configs/nsh -GNinja
This uses ninja generator (install with sudo apt install ninja-build). To build:
$ cmake --build build
menuconfig:
$ cmake --build build -t menuconfig
--------------------------
2. cmake/build: reformat the cmake style by cmake-format
https://github.com/cheshirekow/cmake_format
$ pip install cmakelang
$ for i in `find -name CMakeLists.txt`;do cmake-format $i -o $i;done
$ for i in `find -name *\.cmake`;do cmake-format $i -o $i;done
