Geometry Nodes: new Image Texture node

This adds a new image texture node for geometry nodes. It does not
reuse the same node that is used in shading, because we want to be
able to expose the image and frame as sockets.

There is a known update issue when a movie or image sequence is
used. That will be fixed separately (also see D12957).

Currently, the image socket is just a pointer to an Image ID data block.
This can contain single images but also movies and image sequences.
In the future, the definition of an image socket can be expanded to
include images that are generated from scratch in the node tree.
For more details read the discussion in D12827.

Some of the code is a direct port from cycles and should be cleaned
up a bit in the future. For example `image_cubic_texture_lookup`.

For still images, the frame input is ignored. Otherwise, the frame
has to be in a valid range for the node to work. In the future we
may add e.g. automatic looping functionality.

Cleanup: rename Outliner function

Seems like typos in rB32dc085289ac

outline_batch_delete_hierarchy --> outliner_batch_delete_hierarchy

Fix T91411: Outliner crash using contextmenu operators from a shortcut

Oversight in {rBb0741e1dcbc5}.

This was guarded by an assert in `get_target_element`, but it can be
valid to have these assigned to a shortcut (and then perform the action
without an active outliner element).

Now remove the assert and let the operator polls check if we really have
a target element.

note: this basically makes `get_target_element` obsolete, could call
`outliner_find_element_with_flag` instead in all cases.

Spreadsheet: fix updating active domain when component type changes

The mesh and instances case wasn't handled before.

Cleanup: asset catalog path test, improve sub-test separation

Put related lines in a block of their own, such that each block doesn't
have access to the variables of the previous blocks.

This makes it easier to correctly copy-paste some tests, as the compiler
forces you to update the code afterwards.

Asset Catalogs: be more accepting of backslashes as separators

Asset Catalog Paths should only contain forward slashes as separators, but
now the UI is more resilient to people using blackslashes instead.

Fix T92073: Cycles flicker when panning in camera view with border render

Panning in camera view makes the border to be modified, which was causing
the Cycles display to believe the rendered result is unusable.

The solution is to draw the render result at the display parameters it was
updated for. This allows to avoid flickering during panning, zooming, and
camera FOV changes. The suboptimal aspect of this is that it has some jelly
effect, although it is on the same level as jelly effect of object outline
so it is not terrible.

BKE Callbacks: more explicit initialisation check

Add static boolean to track whether the callbacks system has been
initialised. This makes it possible to make the `BKE_callback_remove()`
function more noisy in case of programming errors, and avoids accessing
`funcstore->alloc` when `funcstore` was potentially already freed.

Thanks @campbellbarton for pointing this out.

Fixes T91294.

Geometry Nodes: use vector socket for offset in Set Position node

This replaces the boolean Offset input in the Set Position node with
a vector input. This makes the node easier to use. Using a "Position"
input as an "Offset" sounds wrong anyway.

The Position and Offset inputs are evaluated at the same time.

The versioning only works correctly when the Offset input was not connected
to something else before.

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 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.
