mesa: Add helper to convert a GL format and type to a mesa (array) format.

v2 after review by Jason Ekstrand:
- Move _mesa_format_from_format_and_type to glformats
- Return a mesa_format for GL_UNSIGNED_INT_8_8_8_8(_REV)

v3:
- Adapted to the new implementation of mesa_array_format as a plain uint32_t
  bitfield.
