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.

Make preprocess-generated outputs depend on included files by
emitting depfiles for GNU/Clang Ninja/Makefile builds.
This fixes stale generated rc.sysinit and ROMFS images when a
board-specific included fragment such as rc.sysinit.ap changes,
because the previous custom command only depended on the top-level
source file.

the -fmacro-prefix-map compile option is gcc/clang/armclang specific
compile option, and greenhills do not recognize this compile option, if
we add this option is CMakeLists.txt, the following warning will be
