Geometry Nodes: remove empty mesh component in distribute node output

Fix T91766: NLA Editor - Segmentation fault on strip resize

NLA and Dope Sheet use a specific transform operation to scale.

Unlike the conventional resize operation, `TIME_SCALE` operates on `td->val`.

This is a bit outside the convention of transform operators.

The expected thing in this case would be to work in `td->loc` and use the conventional resize operator.

But for now, to fix the problem, use `td->loc` in the `TIME_SCALE` operation.

This commit also brings a cleanup in the style of some comments and removing unnecessary `memset`.

Assets: Clear Asset operator variants for clearing/setting Fake User

The Clear Asset operator (`ASSET_OT_clear`) now clears the Fake User.
This makes it symmetrical with the Mark Asset (`ASSET_OT_mark`)
operator, which sets Fake User to ensure assets are always saved to
disk.

Clear Asset now also has a `set_fake_user` boolean option, which allows
users to Clear Asset and set Fake User in one go.

The asset browser now shows these options in the context menu:
- Clear Asset: also clears Fake User. This makes it possible to actually
remove assets from the blend file without leaving the Asset Browser.
- Clear Asset (Set Fake User): keeps the Fake User bit set. This makes
it possible to "hide" the asset from the asset browser, without
loosing the actual data.

Internally, the `ED_asset_clear_id(id)` function now always clears the
Fake User bit. If it was intended that this bit was kept set, it's up to
the caller to explicitly call `id_fake_user_set(id)` afterwards.

Viewport Compositor: Support multiple render layers

This adds the new DRWRenderScene structure (and its sub structures) that
contains all the needed render passes for each scene present in the
compositor nodetree.

The scenes are rendered using a special option to avoid rendering overlays.

The render layer input to the GPUMaterial are now a separate structure and
a separate list of input handled by the compositor engine.

Rendering all scenes is the first thing done to avoir much trouble with

There are still issues like continuous rendering of TAA because the same
DRWData is used for all scenes.

Fix T91679: Crash when saving bordered render as multilayer exr

The related issue which is fixed by this change is the missing noisy
image pass when denoising and border render is used,

Need to allocate passes after the passes has been copied from the
original render result.

This is a manual cherry-pick of rB741fa8180c4f.

Increase VSE strip channels limit from 32 to 128

The original limit dates back from 2002 when Blender went open source.
After that many years some productions (e.g., Sprite Fright) are already
experiencing limitations for complex edits.

The future plans is to support an initial shorter (2?) number of
channels with support to "unlimited" channels.

Finally, I'm bumping the minimum file requirement since files with more
than 32 channels won't work well in old Blender versions.

In a future commit I will implement a sanitization so that we only read (and write)
128 channels. Making sure future changes of this number won't corrupt Blender.

Geometry Nodes: move legacy nodes to separate folder

Previously, we were moving them one by one. It's a lot easier
to just move all files at the same time.

Fix Drivers Editor not hiding vertical part of cursor

When "Show Cursor" is unchecked, the Drivers Editor would still display
the vertical line representing the cursor x.

Probably overseen in {rB65072499c65a} (historically the vertical line
could represent either the current frame of the cursor X in drawing, but
this is now much more separate).

There is no point in seeing part of the cursor in the Drivers Editor if
this is disabled.

Also correct outdated comments.

Fix Drivers Editor showing playhead on the X Axis

Currently the Drivers Editor shows this (the blue thing can be dragged
to change frame):
{F10647661}

But the Drivers Editors X axis is the output of the driver [which can be
further tweaked by the curve] not time(frame).
So it seems better to not mix them here, it is just confusing to have
two different units on one axis.
Especially since what we really want to look at in X (the drivers output
value) can be in a totally unrelated range compared to frames, so e.g.
we might be interested in a drivers range from 0.0 to 1.0 and a
framerange of 100 to 200, so putting this on one axis just does not make
sense. Better to use a separate timeline for this.

Note 2.79 also did not do this.

Path util: BLI_path_contains() case-insensitive on Windows

Make `BLI_path_contains()` case-insensitive on Windows. This behaviour
is dependent on the platform Blender is running on, like the rest of
BLI_path, and not on the style of paths (Windows-style paths will be
treated case-sensitively when Blender is running on Linux/macOS).

VSE: Implement sanity check for files with more channels than supported

This is a follow up to 8fecc2a8525467ee2fbbaae16ddbbc10b3050d46.

This makes sure future .blend files that have more channels than the
