This ensures TGs can be decoded even if the whole
frame has not been received and the frame length
is not known.

This is a manual adaptation of the following commit from aom/master:
ce12003d60a1c8d6c65ed07ba165c34062fcbcbd
The original commit message:
A tile group is a set of tiles in scan order.
Each tile group has a version of uncompressed and compressed headers,
identical apart from tile group parameters.
Encoding probability updates takes account of the number of
headers to control overheads.
The decoder supports arbitrary numbers of tile groups with
arbitrary number of tiles. The number of tiles in a TG is
signalled in the uncompressed header for that TG.
The encoder currently only supports a fixed number
of TGs (3, when error resilient mode is on) of equal size
(except possibly for the last one).
The average BDR performnce with 3 tile groups versus
anchor with error resilient mode and up to 16 tiles is:
NR YCbCr: 3.02% 3.04% 3.05%
PSNRHVS: 3.09%
SSIM: 3.06%
MSSSIM: 3.05%
CIEDE2000: 3.04%

Previously, when ext-partition-types and either clpf or dering were
enabled, the signalling for clpf/dering would not be encoded or decoded,
as the code to do so was inside a #if !CONFIG_EXT_PARTITION_TYPES block.
This caused many tests (eg, AV1/EndToEndTestLarge.EndToEndPSNRTest/0)
to fail with encode/decode mismatches.

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.

By default, when building with --enable-accounting the bit accounting
code will collect statistics for every frame while decoding.
Collecting statistics can slow down decode time and we would eventually
like to enable the CONFIG_ACCOUNTING flag by default.
This patch adds a runtime flag so that bit accounting statistics are
only collected when actually needed.
