Boolean exact: speedup when there are many components.

When there are many components (separate pieces of connected mesh),
a part of the algorithm to determine component containment was slow.
Using a float version of finding the nearest point on a triangle
as a prefilter sped this up enormously. A case of 25 icospheres
subdivided twice goes 11 seconds faster on my Macbook pro with this
change.

Boolean exact: speedup by parallelizing a plane calculation.

This patch is from erik85, who says:
This patch makes populate_plane inside polymesh_from_trimesh_with_dissolve run in parallel.
On a test file with a boolean between two subdivided cubes (~6 million verts) this gives a 10% speed increase (49.5s to 45s) on my 6 core CPU.

Also there is an optimization of other_tri_if_manifold to skip the contains-call and get the pointer directly.
This reduces CPU time for find_patches from 5s to 2.2s on the same test file.

FFmpeg: Fix H264 lossless render not lossless

While encoder parameters for lossless encoding are set correctly,
output is not lossless due to pixel format being set to
`AV_PIX_FMT_YUV420P` which is inherently lossy due to chroma subsampling.

This was reported in T61569 and was merged to T57397, but there were
2 bugs - one for encoding and one for decoding.

Set pixel format to `AV_PIX_FMT_YUV444P` when rendering lossless H264
files. This format isn't available in `codec->pix_fmts[0]` and it looks,
that it has to be hard-coded.

FFmpeg: Update proxy settings

Changes in rBce649c73446e, affected established proxy codec preset.
Presets were not working and all presets were similar to `veryfast`.
Tunes are now working too, so `fastdecode` tune can be used. I have
measured little improvement, but I tested this only on 2 machines and
I have been informed that `fastdecode` tune does influence decoding
performance for some users.

Change preset from `slow` to `veryfast` and add tune `fastdecode`

Fix T57397: Movies are blurred after sws_scale

Images with 4:2:2 and 4:4:4 chroma subsampling were blurred when
`SWS_FAST_BILINEAR` interpolation is set for `anim->img_convert_ctx`.

Use `SWS_BILINEAR` interpolation for all movies, as performance is
not impacted by this change.

VSE: Add strip-time intersection test function

Use SEQ_time_strip_intersects_frame function to test if strip intersects with frame.

Note: There are cases where this function should not be used. For example splitting
strips require at least 1 frame "inside" strip. Another example is drawing, where
playhead technically doesn't intersect strip, but it is rendered, because current
frame has "duration" or "thickness" of 1 frame.

IDManagement: Collection: Fix several issues in relationships building code.

`BKE_main_collections_parent_relations_rebuild`,
`BKE_collection_parent_relations_rebuild` anf their internal
dependencies had two issues fixed by this commit:

* Main one was that a same collection could be processed several times,
sometimes even in an infinite loop (in some rare corner cases), by
`collection_parents_rebuild_recursive`.
* More exotic, code here would not ensure that the collections it was
processing were actually in Main (or a master one from a scene in
Main), which became an issue with some advanced ID management
processes involving partially out-of-main remapping, like liboverride
resync.

LibOverride: ensure proper indirect tag for 'virtual' linked IDs.

Ensure 'virtual' linked override IDs generated by the recursive resync
process are tagged as indirectly linked data.

This is needed to avoid the 'missing data' messages on those virtual
data-blocks after saving and reloading.

Cleanup: make format

Fix T88762: UI using tab to enter next button could clamp the hard min/
max unneccessarily

Since rB298d5eb66916 [which was needed to update buttons with custom
property range functions correctly], using tab would always clamp
(hardmin/hardmax) properties which were using FLT_MAX / INT_MAX as range
in their property definitions.

The clamping of rB298d5eb66916 was copied over from rB9b7f44ceb56c
[where it was used for the softmin/softmax], and while the re-evaluation
of hardmin/hardmax is needed for custom property range functions, the
clamping should actually not take place.

There are many properties using FLT_MAX / INT_MAX etc. and while it
probably would be good to update these with ranges that make more sense
-- not using FLT_MAX / INT_MAX would not have done the clamping here --
there should not be an arbitrary limit to these and they should stay as
they are.
