mesa/formats: only do type and component lookup for uncompressed formats

Browse Source 
Only uncompressed formats have a non-void type and actual
components per pixel. Rename _mesa_format_to_type_and_comps
to _mesa_uncompressed_format_to_type_and_comps and require
callers to check if the format is not compressed.

v2. include compressed format cases to avoid gcc warnings (Chad).
