Sparse support was original introduced in #43776. This commit introduces sparse support as part of Zephyr SCA tool infrastructure. The implementation in this commit has some benefits over existing support: - It does not required users to set `REAL_CC` in environment before invoking build command. This reduces risk of user mistakes, such as - REAL_CC being different from CMAKE_C_COMPILER. - User running CMake in one terminal / environment where REAL_CC is defined but invoking the build command in a different terminal / environment where REAL_CC is not defined or defined differently. - It improve user experience as the user no longer has to define / re-define REAL_CC when building for different architecture, like switching from arm to xtensa, as this is now handled in CMake. - CMAKE_C_COMPILER is not overwriting, this can be important for other tools which calls the C compiler for pre-processing purposes, such as devicetree and linker script generation.
