Cycles: make ambient occlusion pass take into account transparency again

Taking advantage of the new decoupled main and shadow paths. For CPU we
just store two nested structs in the integrator state, one for direct light
shadows and one for AO. For the GPU we restrict the number of shade surface
states to be executed based on available space in the shadow paths queue.

This also helps improve performance in benchmark scenes with an AO pass,
since it is no longer needed to use the shader raytracing kernel there,
which has worse performance.

Cleanup: some renaming to better distinguish main and shadow paths

Cycles: more accurately count main paths for adding work tiles

Easy now thanks to the main and shadow path decoupling. Doesn't help
in an benchmark scene except Spring, where it reduces render time by
maybe 2-3%.

Geometry Nodes: Fields version of Curve to Points node

This commit adds an updated version of the curve to points that
supports fields. Only the position and radius are transferred
by default now, which should improve performance. The other outputs
like tangent and rotation are outputted with anonymous attributes.

I took the opportunity to change a few other small things:

- Name geometry sockets "Curve" and "Points" like other nodes.
- Remove the radius multiple of 0.1, which was confusing.

Thanks to @Johnny Matthews (guitargeek) for an initial patch.

Fix T89771: Cloth disk cache is not read on library overrides when original linked data is already set to use 'Disk Cache'

Yet another try at that hairy issue... See comment in commit for
details, essentially this extend the workaround introduced in Objects'
`lib_override_apply_post` callback to try to also properly 're-use'
`OUTDATED` and `BAKED` flags from old source liboverride into new
destination one.

Cleanup: Add check whether to remove an anonymous atttribute

Add a higher level check that can be used instead of checking whether
the attribute ID is anonymous and checking whether it has any strong
references.

Fix T92368: LMB mouse events (Selecting, doubleclicks etc) are broken

Fix T92347: Append function excludes Collections that do not contain Objects directly.

Collections directly selected by the user should always be
instantiated.

Regression from recent append code refactor.

Cleanup: silence Warnings

Warning C4100 unreferenced formal parameter
Warning C4242 conversion from 'int' to 'short', possible loss of data

Cleanup: use an array for wmEvent cursor position variables

Use arrays for wmEvent coordinates, this quiets warnings with GCC11.

- `x, y` -> `xy`.
- `prevx, prevy` -> `prev_xy`.
- `prevclickx, prevclicky` -> `prev_click_xy`.

There is still some cleanup such as using `copy_v2_v2_int()`,
this can be done separately.

Fix T91243: Object modes are not loaded correctly in inactive scenes.

Do not try to preserve edit modes of objects in non-active scenes (at
least for now), except for Pose mode.

Code was also slitghly refactored (reducing indent levels), and
comments about expected behaviors and known limitations were added.

HIP device code cleanup and fix for high VRAM usage

This patch cleans up code for HIP device and makes it more consistent with the CUDA code.
It also fixes the issue with high VRAM usage on AMD cards using HIP allowing better performance and usage on cards like 6600XT.
Added a check in intern/cycles/kernel/bvh/bvh_util.h to prevent compiler error with hipcc

Asset Browser: Show current file assets in other asset libraries if contained

If the current file is saved within an asset library, showing that asset
library in the Asset Browser will also display the assets from this current
file now. In fact, it's the latest state of the open file, including all
unsaved modifications.
These assets will show a little Blender icon in the preview image, which is our
usual icon for current file data.

Note that this means an important design change: The "Current File" asset
library isn't the only place to edit assets from anymore. From now on assets
from the current file can also be edited in the context of the full asset
library. See T90193 for more info.

Technical info:
Besides just including the assets from the current `Main`, this requires
partial clearing and reading of file-lists, so that asset operations (e.g.
removing an asset data-block) doesn't require a full reload of the asset
library.

View3D: Cursor Snap Refactor

Make the snap system consistent with the placement tool and leak-safe.

**Changes:**
- Store `SnapCursorDataIntern` in a `static` variable;
- Initialize (lazily) `SnapCursorDataIntern` only once (for the keymap).
- Move setup members of `V3DSnapCursorData` to a new struct `V3DSnapCursorState`
- Merge `ED_view3d_cursor_snap_activate_point` and `ED_view3d_cursor_snap_activate_plane` into `state = ED_view3d_cursor_snap_active()`
- Merge `ED_view3d_cursor_snap_deactivate_point` and `ED_view3d_cursor_snap_deactivate_plane` into `ED_view3d_cursor_snap_deactive(state)`
- Be sure to free the snap context when closing via `ED_view3d_cursor_snap_exit`
- Use RNA properties callbacks to update the properties of the `"Add Primitive Object"` operator
