Asset Browser: Activate a catalog when dragging

Without this it's easy to loose track of which catalog you are dragging.
Things feel generally quite jumpy/disconnected, activating the catalog
makes things feel far less like that.
I consider this an important usability fix, therefore I'm adding it to
the release branch.

Asset Browser: Fix catalog being renamed when dropping into parent

When dropping catalogs it is ensured that the name of the moved catalog
is unique within the new parent catalog. When dropping a catalog into
the parent, the catalog would not actually move to a different location,
but it would still be renamed. The unique name logic simply isn't smart
enough to ignore the catalog that is about to be moved.
Address this by disallowing dragging a catalog into its own parent. It's
already there.

BLI: add slice method to index mask and generic span

Geometry Nodes: use simpler types when devirtualizing virtual array

The compiler is more likely to optimize away the function call
overhead when the used type is simpler and not virtual.

Asset Browser: Support dragging catalogs into top level

This was an oversight when I added catalog drag & drop support. I forgot
to add this for dragging catalogs into the top level by dragging into to
the "All" item as well. This made the drag & drop support rather broken
because it wouldn't work for a basic case.

Geometry Nodes: reduce thread switching in evaluator

When a node is executed, it usually schedules other nodes.
Right now, those newly scheduled nodes are added to a
task pool so that another thread can start working on them
immediatly.

However, that leads to the situation where sometimes each
node in a simple chain is executed by another thread. That
leads to additional threading overhead and reduced cache
efficiency (for caches that are not shared between cores).

Now, when a node is executed and schedules other nodes,
the first of those newly scheduled nodes will always be
executed on the same thread once the current node is done.
If it schedules more than one other node, those will be
added to the task pool as before.

The speedup achieved by this is hard to measure. I found it
to be a couple percent faster in some extreme cases, not
much to get excited about. It's nice though that the number
of tasks added to the task pool is commonly reduced by a
factor of 4 or 5.

Fix T92120 (partially): No bone custom shape with curve object meshes

This part of the drawing code assumes that the bone custom object
has only one evaluated geometry component, and it also uses the
object type to check which data to draw, with the functions like
`DRW_cache_object_surface_get` that just take an object input.
Those functions usually work on evaluated objects, which use the
instancing system to access a temporary object with `object.data`
replaced for data types that don't match the original object.

That assumption used to work, but now curve, point cloud, or volume
objects can have an evaluated mesh which is not accessed with the
same object for render engine drawing.

The "correct" solution for the way this code is structured would be to
loop through all of the geometry components and try to get GPU batches
from every one of them. However, that significantly increases complexity
in an area that should probably be refactored anyway. This patch treats
the mesh as a special case, and only draws the evaluated mesh.

The **best** solution in my opinion might be refactoring this area to
use the instancing system with some sort of viewport-only flag so
the custom shape instances aren't added in the render.

The solution is "partial" because the "Wireframe" option only works
for meshes from mesh objects, even after this fix, and because other
data besides meshes is not displayed at all.

Cycles: Add support for building with OptiX 7.4 SDK and use built-in catmull-rom curve type

Some enum names were changed/removed in OptiX 7.4, so some changes are necessary to
make things compile still.
In addition, OptiX 7.4 also adds built-in support for catmull-rom curves, so it is no longer
necessary to convert the catmull-rom data to cubic bsplines first, and has endcaps disabled
by default now, so can remove the special handling via any-hit programs that filtered them
out before.

Cleanup: formatting

Fix inconsistent UI terminology for tiling option

UI: Fix alignment for recently added/edited icons

The patch slightly modifies two recently added icons "FILE_BLEND" and
"CURRENT_FILE" to better align them to the pixel grid, and change the
design of "FILE_BACKUP" to avoid alignment and readability issues, as
well as avoiding the outline version of the Blender logo which violates
the official logo guidelines.

Context: add accessors returning selected actions for animation editors.

Add a new 'selected_visible_actions' property to allow querying
actions that are selected in animation related editors for use in
UI and operators. The 'selected_editable_actions' variant excludes
linked actions (the only reason an action can be read-only).

In the Action and Shape Key editors there is only one action
that is specified by the field at the top of the editor.

In Dope Sheet it scans the channel rows and returns all actions
related to the selected items. This includes summary items for
actions and groups.

In Graph Editor, it lists actions associated with selected curves.

The new property is also used for Copy To Selected and Alt-Click.

Animation: allow manually setting the intended playback range for actions.

Some operations, e.g. adding a new action strip to NLA, require
knowing the active frame range of an action. However, currently it
can only be deduced by scanning the keyframes of the curves within
it. This is not ideal if e.g. curves are staggered for overlap.

As suggested by Nathan Vegdahl in comments to T54724, this patch adds
Action properties that allow manually specifying its active frame range.
The settings are exposed via a panel in the Dopesheet and Action Editor.
When enabled, the range is highlighted in the background using a striped
fill to distinguish it from the solid filled regular playback range.

When set, the frame range is used when adding or updating NLA tracks,
and by add-ons using `Action.frame_range`, e.g. FBX exporter.

Animation: allow marking actions as cyclic for Cycle-Aware Keying.

When a manual frame range is set, allow marking an action as having
Cyclic Animation. This does not affect how the action is evaluated,
but the Cycle-Aware Keying option will automatically make any newly
added F-Curves cyclic. This allows using the option from the start
to build the cycle, rather than only for tweaking an existing loop.

The curves are made cyclic when they have only one key, either
after inserting the first key, or before adding the second one.
The latter case avoids the need to manually make the first added
curve cyclic after marking a newly added action cyclic.
