This prepares for the integration of rectangular transform size
into recursive transform block partition.

Use table to replace the arithmetic computation for mapping between
transform block and pixel number. Support automatic scale of block
size and transform block size.

This change is similar to the one done for choose_tx_size_from_rd in
daf841b4a1
It gives a 4% speed-up on bus_cif.y4m with the following settings:
--cpu-used=4 -p 1 --end-usage=q --cq-level=40 --tile-columns=0 --tile-rows=0

Ran some manual sanity checks:
- Verified that the automatically generated encodings match the
hand-written encodings before the patch.
- Verified that the encoded bitstream before/after this patch is
identical.

For a 16x16 pixel block, one needs to allocate 16x16 coefficient
tokens, plus up to 16 eob tokens, per plane. This commit increases
the token allocation size to cover the case where all the transform
blocks are of size 4x4 in format 444.

Given the largest transform size is 32x32, this commmit changes size
estiiation based on the size rounding up to 32 multiples to avoid
insufficient buffer allocations.

This commit increases the minimum size for allocated buffer for
compressed data. The old size underestimated the size needed for
small images with width or height less than 64 pixels.

Previously, we assumed that av1_init_plane_quantizers is always called with
segment_id == xd->mi[0]->mbmi.segment_id (and use the latter to derive the value
of 'qindex' to use in the quantizer). But this is no longer true when supertx
is enabled. This patch instead remembers the value of 'qindex' derived from
the latest call to av1_init_plane_quantizers and uses that directly.

This commit resets the transform size to be the maximum possible
value. It avoids out-of-boundary writing when the ActiveMap is
turned on.

This avoids an encoding segmentation fault in speed 5, due to the
use of uninitialized dummy inter prediction filter buffer in the
dynamic motion vector referencing scheme.

The difference between src and dst will be signed, the error will be
unsigned. The change quiets -fsanitize=integer:
unsigned integer overflow: 4294967295 * 4294967295

It seems that when bit accounting was introduced in
https://chromium-review.googlesource.com/#/c/400658/
there was one place which was accidentally skipped, leading to build failures
with --enable-dering. This patch adds the missing information.
