cc: fix using '-x c*-header' for header files with GCC. (#4334)

Browse Source 
Gcc does not support `x c*-header` when using `-` as input filename,
which is what ALE does.

Rework the feature to only use `-x c*-header` flag when using Clang and
not GCC.

The feature is now also controlled with the variable
`g:ale_c_cc_use_header_lang_flag` and
`g:ale_cpp_cc_use_header_lang_flag`.
