mesa: fix errors when reading depth with glReadPixels
OpenGL ES 3.0 spec 3.7.2 "Transfer of Pixel Rectangles" specifies
DEPTH_COMPONENT, UNSIGNED_INT as a valid couple, validation for
internal format is checked by is_float_depth().
Fix regression caused by 81d2fd91a90e5b2fd9fd74792a7a7c329f0e4d29 in:
ES3-CTS.gtf.GL3Tests.packed_pixels.packed_pixels
Test uses GL_DEPTH_COMPONENT, UNSIGNED_INT only when GL_NV_read_depth
extension is present.
v2: change check in _mesa_error_check_format_and_type to be explicit
for ES 2.0+, desktop OpenGL does not allow this behaviour + uses
this function for both glReadPixels and glDrawPixels validation.
(No Piglit regressions seen with v2.)
