Use transform DCT_DCT if block quantizer is zero

Rupert Swarbrick requested to merge rswarbrick-argon/dav1d:bug-175-dct-dct into master

To figure out the block quantizer, add the frame-level quantizer to any delta from the current segment. If this is zero, we should use DCT_DCT rather than reading the transform type from the bitstream.

See section 5.11.47 of the spec.
