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.

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 = .; } "

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`

when declaring the target to be `nuttx`,create an empty allsyms source file for it;
when the target is declared as something else,the link behavior of the `nuttx` target is cloned
and added to actually generate the allsyms file.
finally use allsyms_nuttx to overwrite the already generated nuttx
and regenerate binary outputs

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.

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

Define `NUTTX_DEFCONFIG` and `NUTTX_BOARD_ABS_DIR` instead of `BOARD_CONFIG`
when reconfiguring a custom configuration,
because ${BOARD_CONFIG} uses a relative path,
it will cause the following error:

Otherwise, it produces a lot of warnings like:
```
ld: warning: object file (/Users/yamamoto/git/nuttx/nuttx/build/libs/libxx/liblibcxx.a(d2s.cpp.o)) was built for newer macOS version (12.7) than being linked (12.0)
```
The mach-o support of objcopy is fragile at best and often results
in a broken output. It's better not to rely on it.
This matches what the non-cmake version does.
otherwise NUTTX_COMMON_DIR is empty if CONFIG_ARCH_BOARD_COMMON is set from menuconfig

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
