mesa: Return INVALID_ENUM for glReadPixels(..., GL_DEPTH_*, ...) on ES 3
I'm not sure if this is the correct fix. The
_mesa_es_error_check_format_and_type function (used above in the ES 1
and 2 cases) was originally added for glTexImage checking and allows
GL_DEPTH_STENCIL/GL_UNSIGNED_INT_24_8 combinations. Using it in ES 3
causes other tests to regress.
Fixes es3conform's packed_depth_stencil_error test.
