vp3: avoid buffer overread in coeff decode

I couldn't measure it to be slower for normal interframe videos.
For the worst case, high-bitrate intra-only videos, it can be 0.7% slower.

Delay translating DCT tokens into coefficients until immediately before IDCT
...
This is generally around 12% faster than the prior method of creating a
linked list for each block as tokens are read, but can be anywhere from
8% to 28% faster depending on file and CPU.

Do MC and IDCT in coding (hilbert) order
...
This increases the slice size to 64 pixels, due to having to decode an
entire chroma superblock row per slice.
This can be up to 6% slower depending on clip and CPU, but is necessary
for future optimizations that gain significantly more than was lost.

This doesn't really matter yet since 4:2:0 1080p has only 3060 superblocks,
