This commit refactors the rate-distortion optimization scheme for
transform block coding. When both ext-tx and var-tx experiments
are turned on, the encoding time for bus_cif at 1000 kbps goes down
from 706377 ms to 666503 ms (5.6% speed-up). The coding statics
remain unchanged.

Change is only for real-time mode, speed > 5, and non-screen content mode.
Bias is based on block size and motion vector level (motion above some threshold).

Helps to improves stability in background from lightning changes.
PSNR/SSIM metrics on RTC set almost no change/neutral (within +/- 0.1).

Jenkins per-commit test need to be expedited as more experiments are
added into the nextgenv2 branch. This patch does the following:

thread test: change the length of test clip from 5 frames to 3 frames;
only test speed 1.
ArfFreq test: marked as "large".

The tests marked as "large" will be removed from per-commit test
(to nightly test).

Only use non-zero threshold(s) for breakout if
the motion level of the current tested mode is low.

These tables were out of sync with the indexing enum since the
refactoring in commit 4f16f119 (change 303389), due to the removal
of the ext_tx_to_txtype lookup table. This patch just puts them
back in order.

This commit re-works the rate-distortion optimization scheme for
transform coding. It improves the overall compression performance.
For derf set, the ext-tx experiment provides 2.27% coding gains,
and the new scheme that integrates multiple transform type selection
and recursive transform block partitioning provides a total of 3.24%
coding gains.

Current threshold is little too strict.

This commit hooks up the rate-distortion optimization system to
fully exploit recursive transform block partition and multiple
transform type. The compression performance of the two experiments
largely adds up. For derf set, ext-tx provides additional 2.1%
coding gains on top of the gains due to recursive transform block
partition (0.69%).

Correctly compute the block size in bit-stream coefficient token
packing. This fixes an enc/dec mismatch at very high bit-rates.
