This moves the superframe index at the beginning of the frame packet.
There's no change in the superframe index format, and it's still
optional.

The token state array was carried over from the old optimize_b.
With hbd and 64x64 transforms on the array uses 128KB. While the array
could be changed to only store tokens, this commit opts to remove
it entirely.

Improves performance on difficult clips at q20 by roughly 2% with
high-bitdepth enabled. Actual speedup should be higher.

This change has no impact on metrics.

Since alpha is Q3, we reduce y_average from Q10 to Q3. As such, the
prediction is reduced from Q13 to Q6. Chroma dc_pred is reduced from Q7
to Q6 in order to match with the prediction.

the existing code in update_boundary info function always set tile
boundary. However, the cdef filter only check tile boundary info but
not the loopfilter_across_tile_boundary_enabled flag. so it always
disable filtering at the tile boundary no matter what the
loopfilter_across_tile_boundary_enabled is.

with this fix, tile boundary info is only set when
the loopfilter_across_tile_boundary_enabled is set to 0. otherwise
it should be ignored.

This change does not impact the bitstream as no loss is incured by using
a fixed point value for the transform size average.

For low bit depth, the transform size average is stored using Q8.10
fixed point format. Worst case, smallest fraction is 1/1024.

When computing alpha, multiple averages are computed, one for each
transform block. The CfL prediction now uses the transform block average
instead of partition block average.

This allows the decoder to build the CfL prediction by using only the
collocated reconstructed luma values for the current transform size and
not the entire partition.
