cmake: introduce GCC_COMPILER_VERSION variable

Introduce GCC_COMPILER_VERSION to be used in Zephyr CMake when knowledge of the current GCC Compiler version is needed and CMAKE_C_COMPILER_VERSION has not been defined yet. CMAKE_C_COMPILER_VERSION is not defined until project() is called. Signed-off-by: Torsten Rasmussen <[email protected]>
