Add support for compiling FW with settings acceptable for clang,
in order to let it perform static analysis on the code.
Clang works mostly on ASTs made out of C code, so there is
no need to build complete signed binary for it.

Unify calls for compiler version and name for XCC and GCC.
Separate conversion of optimization level from Kconfig settings
to compiler flags to separate cmake function, because of usage
in two places.
Read XCC_TOOLS_VERSION from compiler.

CMake has convention of changing relative paths to absolute
for CMAKE_* variables. It does it automatically f.e. CMAKE_C_COMPILER.
However for our tools like objcopy we have to do it manually.
It also helps with integration of CMake in some IDEs.
