BLI: avoid invoking tbb for small workloads

We often call `parallel_for` in places with very variable
sized workloads. When many elements are processed,
using multi-threading is great, but when processing
few elements (possibly many times) using `parallel_for`
can result in significant overhead.

I measured that this improves performance by >20% in
the refactored realize instances code I'm working on
separately. The change might also help with debugging
sometimes, because the stack trace is smaller and contains
fewer irrevelant symbols.

Cleanup: move public doc-strings into headers for 'python'

Fix T93563: Crash subdividing with overlapping tri and quad

The first loop was left out when finding the split edge boundary.

Fix T92308: OptiX denoising fails with high resolutions

The OptiX denoiser does have an upper limit as to how many pixels it can denoise at once, so
this changes the OptiX denoising process to use tiles for high resolution images.
The OptiX SDK does have an utility function for this purpose, so changes are minor, adjusting
the configured tile size and including enough overlap.

Fix T93548: Appended (material) assets don't have a fake user

Since our design is to always keep data-blocks marked as assets on exit,
and our technical design for this is to do this via fake users, ensure
the fake user is set for an appended asset.

Fix T93555: crash when muting nodes with multiple internal links

The crash happened because I was incorrectly and inconsistently assuming
that a socket is part of at most one internal link. However, this is not the case.
In geometry nodes, an input socket can be internally linked to multiple
output sockets. In the general case, an output could also be linked to multiple
input sockets, even though we don't have that in Blender yet.

Dalai gave green light to cherry pick this fix for 3.0.

Blendread: Remove all instantiation logic from `BLO_library_link_` code.

Instantiation is now fully handled by BKE_blendfile_link_append module.

Note that this also allows removal of the `BLO_LIBLINK_NEEDS_ID_TAG_DOIT`
flag.

Part of T91414: Unify link/append between WM operators and BPY context
manager API, and cleanup usages of `BKE_library_make_local`.

Cleanup: Readfile: Remove deprecated `BLO_library_link_copypaste`.

Rewrite of ID paste code in rB3f08488244c0 made this function useless,
ID pasting is now handled by the BKE_blendfile_link_append module too.

Fix T93410: Crash hiding a region from Python used by a popover

Close all active buttons when hiding a region as this can be called
from Python a popover is open from that region.

Failure to do this causes the popover to read from the freed button.

Also rename UI_screen_free_active_but to
UI_screen_free_active_but_highlight since it only frees highlighted
buttons.

Cleanup: FIx build with USD after recent refactor

rB218360a89217f4e8321319035bf4d9ff97fb2658 missed a couple renames in USD code paths.

UI: Fix scaling of HSV cursor when zooming

The small circle used to choose the hue/saturation and value in the
color widget was drawn with a fixed screen space size. Now scale the
circle used as cursor in the color widget based on the zoom. This
could have been part of a9642f8d6130 but the implementation is
different.

Fix T92268: Group input and output nodes have inconsistent padding

The group output node did not have the same size padding as the group
input, leading to the node looking different and actually being smaller.

Cleanup: Rename curve struct fields

These existing names were unhelpful at best, actively confusing at
worst. This patch renames them to be consistent with the terms
used to refer to the values in the UI.
- `width` -> `offset`
- `ext1` -> `extrude`
- `ext2` -> `bevel_radius`

Fix: Add tooltip translation marker to disabled hints

This was overlooked, as it seems there's no way for these strings to be
translated currently. Generally it's not that clear whether `N_` or
`TIP_` should be used in this case, but `TIP_` seems more consistent.
To avoid the cost of the translation lookup when the UI text isn't
necessary, we could allow the disabled hint argument to be optional.

Fix T84710: Instances with only mesh edges or vertices are invisible

Wire-only meshes have a special case in the overlay drawing to give
the wire shader a special color (which avoids the lines being dashed,
somehow). The fast path for duplis didn't have that special case.

UI: Add an option to display the node editor context path

Since we have the overlays popover, it makes sense to allow toggling the

and turns it on by default in existing files.
