Add ARM64 Windows to configure scripts
In order to correctly configure for Windows 10 on ARM, this change adds
a --target value arm64-win64-vs15 to ./configure and adds feature
enable/disable logic for the new platform.
This is merely sufficient for Chromium targeting ARM64 Windows.

Disable tpl model in GF-only GOP structure
The tpl model assumes a relative short stats buffer length. Hence
it is not ready to support GF-only GOP structure where the max
length can go up to 250. Disable tpl model in such setting to avoid
a rare encode failure in GF-only setting.
vpx_dec_fuzzer: Unify single and multi-thread tests

Rescale arf bit budget calculation
To compute the total budget for a depth layer, exclude the count of
frames that have been allocated the bit budget. This improves the
avg PSNR by 0.15% and overall PSNR by 0.25% for lowres and midres
test sets.

Simplify rdmult computation
Recognizing that max dc_quant used in rdmult computation is 21387 and

Modified key frame detection.
Address poor key frame detection in some content.
This patch improves on poor key frame / scene cut detection observed
with some test content. The content in question was letter boxed film
style material and also had quite low contrast. For both 1080P and 4K
multiple genuine scene cuts were being missed.
The changes alter the conditions for marking a transition as a "flash" rather
than a scene change. The new code still deals well with genuine flashes as
observed in the "crew" test clip, without falsely flagging some of the
the scene cuts in the "film" test clip.
The new film test clip also had some "flash" frames caused by a lightning
effect and in one case a flash occurred right before a scene change. This
caused a misplacement of the key frame but has been addressed by a new
clause that requires the coded error for the next frame after a candidate
key frame to be lower than the current frame.
The patch also changes the way in which neutral blocks (similar inter and
inter error) are handled in the candidate key frame decision in a way which
hopefully handles the letter boxed format better.
During wider testing some film clips still had missed key frames but this
patch does improve things. In the case of the initial test clip the encoder
correctly marks all 3 scene cuts vs 0 before the patch.
Testing with our standard (mainly short single kf) derf and NF test clips
is neutral.

Add vpx_internal_error_info to MACROBLOCKD. When corrupted frame

The main decoding thread will detect error too and return error code to

Each thread will signal end of decoding of the frame. Main thread waits
