CMakeDetermineCompiler: Simplify CMAKE_<LANG>_COMPILER default force-cache 

If find_program does not find CMAKE_<LANG>_COMPILER, use set_property()
to force the value to be that of CMAKE_<LANG>_COMPILER_INIT instead of
set().  This allows us to set the value without re-specifying the type
and documentation, thus preserving what find_program set.
