GPencil: Cleanup unneeded variable assign

The variable is assigned below again and the initial value is not used.

BlenLoad: Ensure linked IDs are properly sorted.

So far, linked IDs were not properly sorted at all, only the ones
explicitely linked from WM code would be, but any indirectly linked
data-blocks would end up in some random order in their lists.

While not ideal, this is not a huge issue in itself, but it had bad
side-effects, e.g. causing (recursive) resync of overrides to happen in
random order, leading to mismatches between name indices of newly-generated
override IDs and the one existings e.g.

And in general, it is much better to be consistent here.

Note that the file sub-version is bumped for this commit, since some
sorting (the directly linked IDs which we keep a reference to) should
never need to be re-done after relevant doversion process.

Greasepencil: show pressure curve widgets in the sidebar

These were only showing in the Properties Editor, but there is no reason
to have the panels be different in the sidebar (they should not show in
the top bar though).

Update Camera presets

The (tracking) camera presets have not been updated in the last 7 or
more years, so they are very outdated. I found it pointless to have a
few specific camera models in the list and instead add the most commonly
used sensor sizes/film sizes. This way the list is shorter, easier to
maintain/becomes later outdated, and is more user friendly for most people
who don't own any of the specific cameras. I added the Crop Factor to the
Beginning of the name, so it gets sortet in the correct order and presets
are easier to find based on the size.

GPencil: Change Fill extend lines icon

The icon has been changed to `eye` because is more consistent with other areas.

GPencil: Change Fill Boundary icon

The icon has been changed to `eye` because is more consistent with other areas.

LibOverride: Fix early break in some of the resync code.

This `break` moved out of its braces at some point in the previous
fixes/refctors... :(

Texture Paint: changing paint slots and viewport could go out of sync

When changing to another texture paint slot, the texture displayed in
the viewport should change accordingly (as well as the image displayed
in the Image Editor).

The procedure to find the texture to display in the viewport
(BKE_texpaint_slot_material_find_node) could fail
though because it assumed iterating nodes would always happen in the
same order (it was index based). This is not the case though, nodes can
get sorted differently based on selection (see ED_node_sort).

Now check the actual image being referenced in the paint slot for
comparison.

ref T88788 (probably enough to call this a fix, the other issue(s)
mentioned in the report are more likely a feature request)

windows/deps: Fix TBB build issues.

rB847579b42250 updated the TBB build script
which had some unintended consequences for
windows as the directory layout slightly
changed.

This change adjusts the builder to the new
structure, there are no version/functional
changes.

Nodes: Add Multiply Add to Vector Math nodes

Cycles, Eevee, OSL, Geo, Attribute

This operator provides consistency with the standard math node. Allows users to use a single node instead of two nodes for this common operation.

Edit Mesh: partial updates for normal and face tessellation

This patch exposes functionality for performing partial mesh updates
for normal calculation and face tessellation while transforming a mesh.

The partial update data only needs to be generated once,
afterwards the cached connectivity information can be reused
(with the exception of changing proportional editing radius).

Currently this is only used for transform, in the future it could be
used for other operators as well as the transform panel.

The best-case overall speedup while transforming geometry is about
1.45x since the time to update a small number of normals and faces is
negligible.

For an additional speedup partial face tessellation is multi-threaded,
this gives ~15x speedup on my system (timing tessellation alone).
Exact results depend on the number of CPU cores available.

Fix T88813: Scalable allocator not used on win10

Due to the way we ship the CRT on windows TBB's
malloc proxy was unable to attach it self to
the memory management functions on windows 10.

This change moves ucrtbase.dll out of the blender.crt
folder and back into the main blender folder to side
step some undesirable behaviour on win10 making TBB
once more able to attach it self.

Having this work again, should give a speed
boost in memory allocation heavy workloads
such as mantaflow.

For details on how this only failed on Win10
see T88813

FFmpeg: Fix seeking not returning the correct frame when not using TC index

Fixed the logic for seeking in ffmpeg video files.
The main fix is that we now apply a small offset in ffmpeg_get_seek_pos
to make sure we don't get the frame in front of the seek position when
seeking backward.

The rest of the changes is general cleanup and untangling code.

Cleanup: unused variable

Nodes: move some files to C++

This just moves a couple of files in `space_node` to C++ and fixes
related errors.

The goal is to be able to use C++ data structures to simplify the code.

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`
