Fix T92446: node editor overlays reset automatically

Caused by rBcf72b10075758be971f9806b97db01f98383aba2.

The fix is to only enable the flags when a new node editor is actually created.

Fix T92430: Infinite recursion in some cases in new append code.

Shapekeys, always shapekeys... Since we cannot deal with them as regular
IDs, we need to handle potential recursion cases ourselves here. sigh.

UI: Refactor dropping support for the tree-view API

Introduces a dropping-controller API for the tree-view items,
`AbstractTreeViewItemDropController`. This reduces responsibilities of the main
tree-view item classes, which are already getting quite big. As I expect even
more functionality to be needed for it (e.g. drag support), it's better to
start introducing such controller types already.

Cycles: Revert all host update specific changes

The approach didn't turn out to be that useful after all as there
are unavoidable dependencies of data from the device. For example,
to know whether object intersects volume or not it is required to
run displacement kernels.

The way of splitting host and device updates caused state where
some data is not yet available, causing confusion and leaving
code to be error-prone.

Cycles: More accurate volume stack size calculation

The idea is to allow having a lot of non-intersecting volumes without
allocating volume stack to its full size.

With the F11285472 file the memory usage goes from 1400 MiB to 1000
on the RTX6000 card.

The fix makes it so the integrator work memory is allocated after
scene update which has downside of possible less efficient update
when some textures don't fit GPU memory, but has an advantage of
making proper decision and having a clear and consistent internal API.

Fixes memory part of T92014.

Fix T91931: Thumbnail Missing Region

Fixes a crash when blend thumbnails set to Camera View when there is
no camera, which resulted in use of a null region.

Fix T90633: Frame all doesn't use meta range

This commit fixes T90633, it changes the behavior of the `Frame All`
operation when the user is tabbed into a metastrip: instead of using
the scene timeline's range, `Frame All` uses the current metastrip's
range.

Fix T90855: Transform effect gives inconsistent output

When using downscaled preview size with proxies, transform effect
doesn't compensate for fact, that pixels are effectively larger. There
was compensation for scene render size already.

Use same compensation method as text effect uses for font size.

Fix T90835: Strip snaps to first and second frame

This was caused by strips with single frame input like single image
strip or color strip. their length is always 1, and so content length
was calculated to end after first frame.

There was code handling this case, but it was also checking for
`anim_endofs` and `endstill` values. Anim offset values have no effect
on these strips and still frame value was used incorrectly. So these
chacks can be removed completely.

Fix T90836: Strip snaps to empty space

This was caused by snap to hold offset feature, which calculates strip
content boundary, but it can be outside of strip boundary.

Clamp content start and end values so they are always inside of strip.

Geometry Nodes: Remove repeated instance attribute names in search

This commit makes sure that each attribute name is only added once
when logging geometry values for attribute search.

The `attribute_foreach` function for a single geometry component
deduplicated names, but a much more common situation is to have
more than one component in the instances of a geometry set.

Fix: memory leak after type conversion in geometry nodes group

The leak happened when two things were true:
* Inside of a node group a socket is linked to a Group Input that has
a different type.
* The corresponding input on the parent Group node is not linked.

The conversion happened correctly, but the original value wasn't
destructed.

Cleanup: quiet asan warning because of uninitialized variable

Fix T92327: use default value when field is passed into data socket

Previously, the computed value passed into the data socket could depend
on the actual field a bit. However, given that the link is marked as invalid
in the ui, the user should not depend on this behavior.
Using a default value is consistent with other cases when there are
invalid links.

Cleanup: cross-reference right pointing arrow literal

This value is defined in the UI module, but happens to be used
in string_search.cc too. Note that these references need to be kept in
sync. Use escaped utf-8 sequence since the literal can be avoided.

Also replace BLI_str_utf8_as_unicode calls with constant assignments
as these values are known there is no need to decode a utf-8 sequence.

Cleanup: line length in Python scripts

Cleanup: spelling in comments

Geometry Nodes: Rename node "String Substring"

This patch renames the node "String Substring" to "Slice String"
to conform to the "verb first" naming convention.
Default length is also changed to 10 to make it easier for users
to understand what the node does.
