Fix validation for compressed texture functions. * No validation that the format matched the texture level's format for SubImage calls. * WebGL does not allow the base level to be smaller than the block size. * ANGLE used to allow mips of size 3 when this is disallowed. * Don't early-exit validation when dimensions are 0, imageSize validation happens later.
