[Mesa-dev] [PATCH 4/5] mesa/glformats: add desktop gl checks on _mesa_base_tex_format

There are several internalformat that are not supported on gl es, so
it should return -1 if that is the case. This is needed in order to
get ARB_internalformat_query2 implementation deciding correctly if
a resource is supported or not on opengl es.
FWIW, in some cases, _mesa_base_fbo_format has equivalent checks
for those internalformats, although for this method it is implemented
as a check/break in most cases, to keep consistency within the function.
