Fix condition for turning off denoiser due to high

take effect on key (super)frame.

VP9 SVC: fix crash on scaling partition.
When scaling up partition from lower resolution layer L, mi_row and
mi_col from L must be smaller than mi_rows and mi_cols from L.
Before this change, the condition was based on mi_rows from top layer
divided by 2, which is not necessarily equal to the mi_rows from lower
resolution layer.
Added variable in SVC structure to keep track of mi_rows and mi_cols
from each spatial layer.

If in constrained layer drop mode, avoid setting

Work around ARM64 Windows SDK arm_neon.h quirk
Since the Windows SDK has an ARM32-only arm_neon.h, files including it
during ARM64 Windows builds need to be redirected to arm64_neon.h.
Instead of editing many files to include ARM64-Windows-specific ifdef
logic, this commit introduces an ARM64-Windows-specific version of
arm_neon.h that performs the needed redirection and lands earlier in
the header search path than the ARM32-only arm_neon.h.

vp9: Reorganize the buffer level for cbr mode
Refactor the code with some changes.
Split update into two parts: move the fillup
(with per-frame-bandwidth) before the encoding, and
keep the leaking part (with encoded_frame_size) after
the encoding (postencode).
For SVC with ref_frame_config usage: allow usage of timestamp
delta for the fillup part of buffer, instead of the (average)
framerate passed in via the duration.
Moving the buffer fillup (+per-frame-bandwidth) part to the
pre-encode causes some difference in performance
(since buffer level affects active_worst/QPand frame-dropping),
but the change is observed to be small.
Made small adjustment to active_worst_quality to compensate.
