i965: Disable KHR_texture_compression_astc_hdr on Gen9
Although Gen9 samples from most HDR ASTC surfaces of correctly,
there currently are no software workarounds to fix the incorrect
sampling that occurs in others of certain color endpoint modes.
With this change, we are no longer failing the 14 tests from:
dEQP-GLES3.functional.texture.compressed.astc.endpoint_value_hdr_cem_15.*
