Add wxGCC_ONLY_WARNING_{SUPPRESS,RESTORE} macros

Browse source 
When the original wxGCC_WARNING_SUPPRESS was added, clang understood all
gcc warnings, so it made sense to also apply it when building with
clang, but recent gcc versions have added warnings not available in
clang any more, so we now need a macro for disabling warning the
warnings for gcc only.

Perhaps we should rename the existing wxGCC_XXX macros to use
wxGCC_OR_CLANG prefix.
