BaseTools/Source/C: take EXTRA_OPTFLAGS from the caller

Allow the caller of the top-level makefile either to set EXTRA_OPTFLAGS in
the environment or to pass EXTRA_OPTFLAGS as a macro definition on the
command line. EXTRA_OPTFLAGS extends (and potentially overrides) default C
compilation flags set in the makefiles.
