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

Because `set_source_files_properties` in cmake will overwrite the properties instead of appending them.
This module implements addition and deletion by
first `getting_source_file_property` and then `set_source_files_properties`

Inclusion of mach/mach_time.h by libcxx/src/chrono.cpp breaks
the build on latest MACOS dues to https://forums.developer.apple.com/forums/thread/746737
The interface from mach/mach_time.h is not referenced in chrono.cpp
so it is safe to remove it

It seems libcxx needs C++20 from 12.0.0 to 17.0.6: 3b625060fc
But we're setting CMAKE_CXX_STANDARD to 17, errors on my side:
nuttx/libs/libxx/libcxx/src/include/to_chars_floating_point.h:122:46: error: ‘bit_cast’ is not a member of ‘std’
122 | const _Uint_type _Uint_value = _VSTD::bit_cast<_Uint_type>(_Value);

- Add __config_site for NuttX.
In libcxx 12.0.0. CMake concatenated __config_site with _config,
which enabled NuttX to build without its inclusion. In 15.0.7, this
file is configured by CMake and included explicitly in __config.
- Add additional include directories.
- Mute always_inline warning.
- Make the download of libcxx/libcxxabi configurable
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
