Cleanup: remove unnecessary include

Fix T66040: Make Data Transfer' Mix Factor multiply with vgroup weights when given, instead of ignoring it.

Brings behavior of those options in line with the VGroup editing
modifiers ones e.g.

Alembic: fix heap-use-after-free error

The mesh can be freed by BKE_mesh_nomain_to_mesh(), so we need to get
the `ME_AUTOSMOOTH` flag before that call, and not after.

Fix T61935: load camera transforms from Alembic files written by Meshroom

Meshroom writes two hierarchies to Alembic, one rooted at
`/mvgRoot/mvgCameras` and the other at `/mvgRoot/mvgCamerasUndefined`.
These paths have no schema definition, and thus are ignored by Blender.
The cameras themselves have those schemaless paths as parent, and have
their transforms marked as "inherited", e.g. relative to their parent.
As these cameras have no valid parent, there is no Blender object to use
to convert their local matrices to world matrices, and Blender just
decided to reset them to the unit matrix.

Now "inherited" transforms without a parent in Blender are interpreted
as world transforms. Reparenting those objects to a Blender object will
re-interpret the transforms as local to the parent again.

FFmpeg pixel format conversion improvements

FFmpeg expects Blender to feed it pixels in the output pixel format. If
the output pixel format is different than Blender's RGBA, a conversion
is needed (via FFmpeg's `sws_scale()` function). There were a few issues
with this conversion (and surrounding code) that are fixed in this
commit:

- When conversion was necessary a temporary buffer was allocated and
deallocated for every frame. This is now allocated once and re-used.
- Copying data to the buffer was done byte-for-byte. On little-endian
machines it is now done line-by-line using `memcpy` for a little speedup.
- The decision whether pixel format conversion is necessary is now
correctly done based on the pixel format Blender is actually using.
- The pixel format of the buffer sent to FFmpeg is no longer hard-coded
incorrectly to a fixed pixel format, but uses the actual output pixel
format. This is fixes T53058 properly, making RGB QTRLE export possible.
- I added some comments to make it clear which pixel format is referred
to (either Blender's internal format or the FFmpeg output format).

Combined these improvements not only correct a bug (T53058) but also
results in approximately 5% speed improvement (tested with a 117-frame
shot from Spring, loaded as PNGs in the VSE, encoding to h.264 with
preset 'realtime').
