d77ef098c6 build: set CMake policy to allow FetchContent_Populate
FetchContent_Populate is depracated starting from CMake
3.30. Setting this policy to OLD allows clean CMake builds
for configurations that rely on CMake fetch content feature.

7b4f554f39 cmake: strip file full path to save the code size
Cmake build provide absolute paths to compile files. If __FILE__
macros are used in the source code(ASSERT), the binary will be occupied
by many invalid paths.
This saves some memory, stops leaking user locations in binaries, makes
failure logs more deterministic and most importantly makes builds more
deterministic.
Debuggers usually have a path mapping feature to ensure the files are
still found.

Test config sabre-6quad/citest:

Before:
$ size build/nuttx
   text	   data	    bss	    dec	    hex	filename
 279309	    908	  13652	 293869	  47bed	build/nuttx

After:
$ size build/nuttx
   text	   data	    bss	    dec	    hex	filename
 269313	    908	  13652	 283873	  454e1	build/nuttx

9915b80e30 arch/sim: add custom data section support
The link script of NuttX Simulator is generated through compilation
options. This PR will support configure special data sections in
kconfig to meet the support of 3rd party applications.

we need to follow the syntax of linker script. In 3rd-party applications, some data will be labeled as section:

| a.c:
| struct task_s a __attribute__((section(".data.custom.taska")));
| b.c:
| struct task_s b __attribute__((section(".data.custom.taskb")));

Data of the same type struct can be placed in a fixed location to reduce the overhead caused by searching:

|   .data           :
|   {
|     _custom_data_table_start = .;
|     KEEP(*(.data.custom.*))
|     _custom_data_table_end = .;
|   }

Such section declare can be configured via Kconfig in the PR:

| CONFIG_SIM_CUSTOM_DATA_SECTION=" .data : { _custom_data_table_start = .; KEEP(*(.data.custom.*)) _custom_data_table_end = .; } "

ce61e866c3 CMake:Duplicate definition of CMAKE_CXX_STANDARD
CMAKE_CXX_STANDARD is repeatedly defined in the two files, nuttx/CMakeLists(14) and libs/libxx/libcxx.cmake(17), and is defined to different values. Matter needs to use the new features(std::is_signed_v) of c++17,so delete the definition in nuttx/CMakeLists and retain the definition in libs/libxx/libcxx.cmake.

ea8682572c build/cmake: add initial KERNEL mode support
Currently only FLAT mode development can enjoy cmake build system. This
patch tries to add initial kernel mode support. It can build NuttX kernel
and libproxies.a, the latter will be further checked though.

This can already help to build an AMP remote node image as it can share
userland apps living in the AMP master node.

Major changes:

- in top folder:
  - CMakeLists.txt    adjust for KERNEL mode, separate from PROTECTED mode.
- in `syscall`:
  - CMakeLists.txt    add mksyscall target for stubs/proxies generation
- in `syscall/stubs`:
  - CMakeLists.txt    use dependency to mksyscall
- in `syscall/proxies`:
  - CMakeLists.txt    use dependency to mksyscall
- in `arch`:
  - CMakeLists.txt    separate KERNEL from PROTECTED mode.
- in `arch/risc-v/src`:
  - CMakeLists.txt    separate from PROTECTED mode, add sub folders.
- in `arch/risc-v/common`:
  - CMakeLists.txt    add sources and sub-folders for KERNEL mode.
- in `arch/risc-v/k230`:
  - CMakeLists.txt    add sources for KERNEL mode.
- in `boards/risc-v/k230/canmv230/src`:
  - CMakeLists.txt    adjust k230 specific scripts for kernel mode.

New additions:

- in `arch/risc-v/src/nuttsbi/`           add CMakeLists.txt
- in `arch/risc-v/src/common/supervisor/` add CMakeLists.txt

6ee9ec7656 build: add initial cmake build system
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
