CMake/Deps: Alembic 1.7.16

Version bump + no longer using Boost.

Building Alembic with Boost gave compiler errors, and having one less
inter-dependency is good as well.

Cleanup: Grammar in comments

Cleanup: unused variable

CMake/Deps: XR_OpenXR v1.0.14

Straight up version bump

Things of note:

They started using API calls only available in windows 8, however given
the Python 3.9 update will forcibly bump us to 8.1+ anyhow this is not
an issue.

Will require some minor tweaks to platform_win32.cmake after adding the
libs to svn which are not included in this diff so this diff can land
without having to have the libs in place yet.

Cleanup: Remove code duplication (merge error)

Fix T71960: Malformed .bmp files lead to crash

Add a boundary check, avoiding access past actual data.

Ideally would need to report error to the user somehow,
but it doesn't seem to be easy to do.

This is a minimal safe patch. The proper complete fix is
being worked on by Jesse.

FFmpeg: Improve multi-threading settings for VSE proxies

Following code from D8627 this patch corrects multi threaded processing
of proxies, where a 60 sec proxy generation drops to 35 sec.

FFmpeg: Improve multi-threading settings

Allow use all system threads for frame encoding/decoding. This is very
straightforward: the value of zero basically disables threading.

Change threading policy to slice when decoding frames. The reason for
this is because decoding happens frame-by-frame, so inter-frame threading
policy will not bring any speedup.

The change for threading policy to slice is less obvious and is based on
benchmark of the demo files from T78986. This gives best performance so
far.

Rendering the following file went down from 190sec down to 160sec.

This change makes both reading and writing faster. The animation render
is just easiest to get actual time metrics.
