Specialize the mask update for each PBVH type, simplifying hot loops,
reducing reliance on complex shared state and clarifying which data is
used. Expose functions to update the visibility and masks tags for a
specific node. It can be helpful to call these after modifying the data
to update the flags while the data is more likely to be in CPU caches.
Since we're always writing the mask with the old format, this versioning
will have to run until a larger breaking release such as 5.0. Luckily it
is cheap, it's just rearranging the pointers to larger arrays.
Implements #105001 - new import option for name separator, e.g. "|" or "/".
Names found in the OBJ file are split by that, and a Collection hierarchy is
made, so you can have e.g. "o House/Roof/Tile" in the OBJ file.

Changes:
- Renamed Split Viewer Node to Split Node
- Split Node is now under `Utilities` (similar to Switch node)
- Versioning: split viewer from 4.0 and before is replaced with the new split node connected to a new viewer node.

Instead of allocating a separate bitmap per grid for the hide status, store
all the bits in a recently added C++ data structure that stores all bits in one
contiguous memory chunk. When nothing is hidden, nothing is allocated
(that saves 32 MB for a 16 million vertex multires sculpt). Intuitively it
could have better performance because of the cache benefits of
contiguous memory, but this is hard to measure. It also has a nicer
API than `BLI_bitmap`.
I discussed this with Sergey in person recently. Most of the changes are
just straightforward refactors. The part that isn't is a change to the "show/hide"
operator to structure it similarly to the mesh handling in 4e66769ec0.

This merge does not rename any ID. In case a conflict happens (an ID of
the same name and library already exists in destination Main), its
counterpart in source Main is not moved, and its usages by other
moved-from-source IDs are remapped accordingly.
Libraries are also properly de-duplicated, and remapped as necessary.
Source Main is always freed by this function, since it is either empty,
or contains left-over IDs very likely to have invalid relationships
after the merge.
NOTE: This commit also enables `main_test.cc` unittests, which was
comitted by mistake in fe3cb11ae4, sorry about that.

Usually Library pointers should not be affected by remapping, but this
can be needed in some cases.
WARNING: Use with caution, this is potentially a dangerous operation for
Main data integrity/validity.
Speedup the "apply zebra stripes" image loop by multi-threading it.
For non-float images, avoid an extra image copy that was not doing
anything useful.
4K UHD resolution, Windows Ryzen 5950X:
- LDR: whole `sequencer_get_scope` 16.4ms -> 5.3ms, just `draw_zebra`
part: 7.5ms -> 3.3ms
- Float image: whole `sequencer_get_scope` 126.6ms -> 114.1ms, just
`draw_zebra` part: 22.4ms -> 7.4ms. Whole scope is still expensive
due to color management work being done.

Defer creating events until the "frame" callback runs to ensure
the tablet state has been fully updated before the events are created.
This also avoids redundant motion events which are now only sent
when the motion/pressure or tilt callbacks run.
Updating NLA menu to be more inline with VSE / other Animation editors.
Remove "Edit" drop down, and instead split operators into "Track" & "Strip" Menus. Update Add menu to be more concise.

The position of the vertical value slider has to be clamped to be
within the area of that slider, otherwise it can draw outside the
range when a value is over 1.

While in weight paint mode, `ob.vertex_groups.active` can be None.
This happens when selecting a non-deforming bone, or a deforming bone
that doesn't have a group yet.
Now check for this.

This operator (`SCULPT_OT_reveal_all`) is redundant with
the "Hide Show" operator (`PAINT_OT_hide_show`). Since
the latter was recently changed to be much faster, remove the
former and update keymaps and menus. The industry compatible
keymap actually already contains the hide/show operator.

Move the geometry shading add_operation_node call to

Avoids triggering an assertion when the same geometry data is shared

This function is only used in Sequencer code to convert source byte images
into float images. For a "simple case" where there is no color space
conversion needed, it was doing that on a single thread, in two passes over
the image (first byte -> float conversion, then alpha premultiply).
VSE 4K resolution playback, with two image strips where one of them has
"convert to float" option, on Windows / Ryzen 5950X:
- Overall playback FPS: 3.40 -> 4.03. Still very slow, and a lot of time
is spent in allocating, clearing and deleting various temp images, as
well as final color conversion for display.
- `seq_imbuf_to_sequencer_space` part: 217.9ms -> 86.6ms. Most of
remaining cost is just in just memory allocation+clear, which is why
it's not drastically faster due to threading.

The experimental GPU compositor crashes when the render size is huge.
This is just due to GPU texture allocation failing. The patch fixes that
by downscaling the render result when reading, then upscaling it again
when writing. Additionally, the render size was adapted to the
downscaled size since it is used by other input nodes. This is not an
ideal solution, but it a good temporary solution to prevent crashes
until we have proper support for huge textures.
