Finish reusable frame implementation

Viewport Compositor: Add basic alphaOver node support

Not all feature are supported. For now expect both inputs to be
"premultiplied".

Viewport Compositor: Small fixes

Fix memory leak, a crash when resizing and wrong texture coordinate
in camera mode.

Change render layer sampler name to allow other texture to be bound.

Add skeletal beginnings of C++ sculpt refactor
design study (note that it's #ifdef'd out).

Basic idea is to put all the sculpt brush code
in a single large template. This template
takes a PBVH adaptor class (of which there
would be three, one per PBVH_XXX type)
as a template argument.

Basically we're using the compiler to generate
three complete copies of every brush implementation.
C++20 concepts are used to validate the pbvh classes.

An example brush implementation:

pbvh->forVertsInRange(
{
.brush = ss->cache->brush,
.radius = radius,
.use_threads = true,
.use_original = false
},

[&offset](auto viter, int node_i, void *userdata) {
//add offset to vertex coordinates

madd_v3_v3fl(viter.co, offset, viter.fade);
},

[](PBVHNode *node, int node_i, void *userdata) {
BKE_pbvh_node_mark_update(node);
});

Get basic catalog activation and catalog based filtering to work

It's now possible to activate a catalog in the catalog tree to only make
matching catalogs visible. This doesn't yet show assets from all
sub-catalogs when selecting a parent catalog.

Disable asset category checking in script, avoids warning

For now just always show category specific panels in the Asset Browser,
until we have a proper heuristic implemented for deciding when to show
them, based on catalogs.

Fix wrong render with portals and constant background color

Need to apply MIS weight also in that case.

Fix missing mutex lock for viewport OpenGL context

A mistake in D12468: the viewport uses GHOST to operate on contexts,
bypassing draw manager state,

Cleanup: Typo fix in a comment

Render: Introduce render_frame_finish RenderEngine callback

Allows to inform the engine that nothing else will be rendered for the
current frame and that the engine can perform post-processing of any
pending result.

For example, this allows the engine to free its memory, read all files
from disk and write them to Blender.

Currently no functional changes, just preparing API for the further
development of Cycles on-disk tile storage.

Cycles X: Switch TileManager to use BufferPass

Continuation of work related on making buffers a sufficient entity
to properly access pass pixels.

For the ease of (de)serialization the buffer pass and parameters
are now subclass of Node. Can try looking into adding an explicit
Serializable API, but it will be outside of this patch and not
currently sure it will make things more clear.

Cycles X: Convert DenoiseParams to a "lite" Node

It is not supposed to be a node of a scene graph, but this change
allows to simplify serialization of the denoising parameters.

The goal is to be able to easily (de)serialize denoiser parameters
to/from image metadata, so that processing of the files can happen
outside of the scene graph (for example, on-disk tile buffer and
animation denoising).

Cycles X: Keep track of passes list in BufferParams

Currently should no functional changes.

The goal is to completely decouple BufferParams from Scene graph for
pass accessing.

This is needed for the on-disk tiled storage when EXR is to be read
from disk after the session got freed. Also, will make animation
denoising easier to implement.

Cycles X: Switch PassAccessor to BufferPass

Moving towards pixels access from only Buffers, without access to
the scene graph.

Should be no functional changes.

Fix missing shadow catcher pass in viewport

The regression was caused by changes related on GPUDisplay used for
an offline rendering.

Ensure unique names of tile buffer files in Cycles X

It is possible that processing and deletion of tile buffer from disk
will happen after tile manager was re-allocated. This happens, for
example, when rendering multiple view layers in Blender: each view
layer will reset session (which re-creates the tile manager).

Cycles X: restore support for render progress bar percentage

Support active item in the tree view

Tree view items can now be activated, there is only ever one active
item.

Exact behavior for collapsing vs. activating on click may need some
experimentation. For now I've implemented something that makes sense for
asset catalogs (I think :) ).
