Message : Key the format tables on internal format and type. Keying the format tables on internal format alone is not enough to fully validate the unsized formats which require additional type information. This CL has no functional changes, it just splits the tables and updates the calls to GetInternalFormat info to provide type information when the format is not sized.

// This test enumerates all GL formats - for each, it queries the D3D support for
// using it as a texture, a render target, and sampling from it in the shader. It
// checks this against our speed-optimized baked tables, and validates they would

// TODO(jmadill): Find out why in 9_3, some format queries return an error.
// The error seems to appear for formats that are not supported on 9_3.
