Fix T91808: Batch Generate Previews fails

Caused by the Cycles-X merge.

The old style of tile rendering was removed, leaving the script to error
out trying to set the tile size.

Tile rendering came back in a new form (but only really relevant for
large resolution rendering), so now leave setting auto_tile & tile_size
alone (since previews are rendered at PREVIEW_RENDER_DEFAULT_HEIGHT 128
-- which should never make a difference here).

Cleanup: Remove unused file-list array info members

UI: Activate parent when active child is collapsed

Previously, when an item was active and its parent (or grand parent, etc.) was
collapsed, the active item would simply not be visible anymore. It seemed like
there was no active item. So instead, change the just collapsed parent to be
the active item then, so the active item stays visible.

Asset Browser: UI polish for the asset metadata sidebar

* Show asset path in a (read only) text button. Makes it possible to see the
full path in the tooltip, brings support for copying the path and integrates
better with the sourrounding layout. Previous label needed lots of space to
show the full path without clipping.
* Remove "Details" panel, it only contained one item (description). That is
moved next to the name and asset path button.
* Use property split layout for name source and description buttons. Now that
there are multiple buttons, it's better to have a label for them.
* Always show operators for asset previews, just gray them out if not
applicable instead of hiding. Keeps the layout consistent and graying out is
less confusing than hiding UI elements.

Split and extend unit tests for vec_roll_to_mat3_normalized.

Separate the huge test into huge logical parts and add more cases
to check. Also add a utility to check that the matrix is orthogonal,
with arbitrary epsilon values and calculations in double.

A couple of tests deliberately fail, to be fixed in following commits.

Ref D9551

Fix T82455: vec_roll_to_mat3_normalized returns NaN when nor close to -Y.

In this case theta is completely unsafe to use, so a different
threshold based on x and z has to be used to avoid division by zero.

Ref D9551

Fix precision issues and a bug in vec_roll_to_mat3_normalized.

When the input vector gets close to -Y, y and theta becomes totally
unreliable. It is thus necessary to compute the result in a different
way based on x and z. The code already had a special case, but:

- The threshold for using the special case was way too low.
- The special case was not precise enough to extend the threshold.
- The special case math had a sign error, resulting in a jump.

This adds tests for the computation precision and fixes the issues
by adjusting the threshold, and replacing the special case with one
based on a quadratic Taylor expansion of sqrt instead of linear.

Replacing the special case fixes the bug and results in a compatibility
break, requiring versioning for the roll of affected bones.

Link/Append tests: properly support and test with/without 'recursive' behaviors.

This requires adding an extra ('indirect') library to the test cases for
append.

Aftermath of T92224.

Tracking: support editing all selected tracks

This patch adds a "selected_movieclip_tracks" context member and enables
editing properties of multiple selected tracks via the usual Alt-click
editing (as well as the "Copy To Selected" operator). Both use
UI_context_copy_to_selected_list() to gather a list of other selected
items [which are now taken via said new context member]. Strictly
speaking, this could be done without the context member as well [just
gathering other selected tracks in UI_context_copy_to_selected_list()
without relying on a context member], but this might come in handy in
other places (e.g. Addons).

note: some could be desired for markers (e.g. editing pattern/search
areas of all selected track markers, but since this is burried in a
uiTemplate, this is a bit more work for another patch).

View3D: expose snap selection as a utility funciton

This makes it convenient to position appended objects, see: T92111.

View3D: snap with active pivot doesn't need to require a 3D view

Fix : Set Curve Handle Position Node Auto Convert

When trying to auto convert Vector to Free or Auto to Align, the
old handle positions needed to be baked in first.

CMake: add WITH_BLENDER_THUMBNAILER option

Make building the thumbnail extraction executable optional,
disable on macOS as this was not linking, further, macOS doesn't use
this for thumbnail extraction so it could be left disabled.

Cleanup: use elem macros

Thumbnails: refactor extraction to use one code-path for all platforms

Thumbnail extraction now shares code between Linux/Windows,
allowing thumbnails from Zstd compressed blend files to be extracted.

The main logic is placed in blendthumb_extract.cc and is built as static
library. For windows there is DLL which is registered during blender
install and which then reads and generates thumbnails.

For other platforms there is blender-thumbnailer executable file which
takes blend file as an input and generates PNG file. As a result
Python script blender-thumbnailer.py is no longer needed.

The thumbnail extractor shares the same code-path as Blenders file
reading, so there is no need to duplicate any file reading logic.
This means reading compressed blend files is supported (broken since
the recent move Zstd compression - D5799).

This resolves T63736.
