Upgrade texture parameter validation to accormodate both ES2 and ES3.
In ES2, internal format matches format, but in ES3 that's no longer the case.
So we build a (internal_format, format, type) table.
This table can be unconditional because we validate internal_format, format,
type according to whether an extension is exposed or not.
Also, this CL tries to make SubTexImage3D mostly correct (except for the
clean bit part).
