This change fixes NuttX’s CMake support when NuttX is embedded
in another project via add_subdirectory(). CMake’s CMAKE_SOURCE_DIR
and CMAKE_BINARY_DIR refer to the outermost project, causing NuttX
to access its .config, generated files, host tools, and build artifacts
in the parent project’s directories. The fix introduces NUTTX_DIR and
NUTTX_BINARY_DIR, based on CMAKE_CURRENT_SOURCE_DIR and
CMAKE_CURRENT_BINARY_DIR, and consistently uses them for NuttX
self-references while preserving existing standalone builds. It fixes
the Kconfig initialization failure reported in #19697 and allows an
embedded sim:nsh build to configure, build, and boot successfully.
The change affects only the CMake build system (not Make or Kconfig
defaults), requires the corresponding nuttx-apps change, and does not
extend add_subdirectory() support to cross-compiled non-sim boards due
to CMake’s toolchain-file limitation.
Fixes#19697.

1. enhanced process_config.py script: supports both preprocess and postprocess modes
2. in preprocess mode: handles include formats and recursively records the include config tree structure to prepare for postprocess
3. In postprocess mode: compares the original file with menuconfig to identify non-#include items that should be written back
4. olddefconfig stores the original compressed include defconfig file at the very beginning
5. savedefconfig saves both the original file and the written back include defconfig

- CMake added board Raspberry Pi Pico
- Added the entry:
CMake,raspberrypi-pico:bmp280
to the file arm-06.dat.
- Moved the search for the Python 3 interpreter to the
root CMakefile to avoid unnecessary repetition.

Add:
cmake/nuttx_process_config.cmake
tools/process_config.py
Update nuttx/CMakeLists.txt to call process_config defined ini
nuttx_process_config.cmake to process defconfig before actually using it
