Fix T90127: Merge Down layer doesn't take the transform location into account

Now the layer transformation is applied before the merge.

Cleanup: Fix compiler warning in previous commit

LayerCollections: Add a way to prevent their resync with Collection hierarchy.

This is an easy & safe, yet not-so-nice way to address the
LayerCollections vs. Collections hierarchy resync problem.

Currently this resync is enforced everytime something changes in the
Collections hierarchy, which is extremely inneficient, and can even
produce 'loss' of LayerCollection data during complex Collection
processes.

Current example is during Library Overrides resync process. New code:
* Makes resync significantly faster (between 10 and 15%).
* Fixes 'disappearing' layer collections settings on sub-collections'
layers.

NOTE: This is not a proper fix for the underlying issue. However,
implementing and testing the 'lazy update' solution as proposed by
{T73411} requires a significant amount of time (especially in testing
and tracking all places where code would need to ensure LayerCollections
are up-to-date), which is not possible currently.

Cycles: upgrade CUDA to 11.4

This fixes a performance regression on Ampere cards, on specific scenes like
classroom. For cycles-x there is little difference, but this is still helpful
for LTS releases, and we need to upgrade at some point anyway.

Compositor: Full frame Scale node

Adds full frame implementation to this node operations.
No functional changes.

Includes a new operation method `init_data` used to initialize any data
needed after operations are linked and resolutions determined.
Once tiled implementation is removed `initExecution` may be renamed
to `init_rendering` and `init_data` to `init_execution`.

Fix: Instantly hide bones after hitting H key in pose sliding

When using a pose slider it is possible to hide bones with the 'H' key.
Before this patch the screen didn't update, so you had to move the mouse 1 pixel to update.
This patch makes it so it updates right away

Fix T90026: attributes added in editmode are lost on modeswitch

When exiting editmode, customdata [and thus attributes] are copied from
**BMesh** to **Mesh** (in `BM_mesh_bm_to_me`).
When adding attributes, these were always added via
`CustomData_add_layer_named` only.
Instead (if we are in mesh editmode), we need to go through
`BM_data_layer_add_named` to properly update the **BMesh** (see
`update_data_blocks`) so we have stuff available to copy back to
**Mesh** when exiting editmode.
Same is done for removing (also going through BMesh).

This is now done, DomainInfo is updated to point to BMesh (instead of
Mesh) customdata when in editmode.
