Experimental: add B-Bone lengthwise scaling options.

- Option to actually apply Y scale to segments (for backward compat).

Refactor/extend BKE API to get special user directories

The previous `BKE_appdir_folder_default()` was confusing, it would return the
home directory on Linux and macOS, but the Documents directory on Windows.
Plus, for the Asset Browser, we want to use the Documents directory for the
default asset library on all platforms.
This attempts to clean up the API to avoid confusion, while adding the newly
needed functionality.

* `BKE_appdir_folder_default()` should behave as before, but the implementation
changed:
** Removes apparently incorrect usage of `XDG_DOCUMENTS_DIR` on Unix systems -
this seems to be a config file variable, not an environment variable. Always
use `$HOME` instead, which this ended up using anyway.
** On Windows it doesn't attempt to use `%HOME%` anymore and gets the Documents
directory directly.
* Add `BKE_appdir_folder_home()` to gives the top-level user directory on all
platforms.
* Add `BKE_appdir_folder_documents()` to always get the user documents
directory on all platforms.

There should be no user noticable behavior change.

Ghost: Support queries for special user directories (desktop, documents, etc.)

When we had to get special user directories, we'd usually do it in varying,
rather ad-hoc ways. It would be done with a bunch of `#ifdef`s for the
different operating systems. Also, some of the used Win32 functions were legacy
ones and the API docs recommend using newer ones.
Further, seems `BKE_appdir_folder_default()` used `XDG_DOCUMENTS_DIR` wrong.
It's not supposed to be an environment variable but a value inside a config
file.

This adds the platform dependent logic to Ghost, so we can abstract it away
nicely using the `GHOST_ISystemPaths` interface. Getting the desktop directory
for example can now easily be done with:
`GHOST_getUserSpecialDir(GHOST_kUserSpecialDirDesktop).`

For now I added the logic for desktop, documents, downloads, videos, images and
music directories, even though we only use the Documents one. We can extend/
change this as needed, it's easy to do now.
On Windows and macOS, it uses pretty much the same way to access the
directories as elsewhere already. On Linux, it uses the `xdg-user-dir` command
that seems to be available by default on most Linux systems.

No functional changes. The new queries are not actually used yet.

Fix T82881: Paint mask 'deselect on nothing' missed viewport update

Was failing for weightpaint and vertexpaint.

Selection flags were actually changed, but the update in the viewport
wasnt immediate, leading to confusion when the update happened later
(e.g. when using the weight gradient tool as done in the report).

We need to tag ID_RECALC_SELECT and send ND_SELECT notifier here. This
could be done explicitly, but there is also existing functionality
available that does this.
Note: the way updates happen for paintfaces vs. paintverts looks a bit
inconsistent (so this could be part of a later cleanup commit)

Cycles: Add CPU+GPU rendering support with OptiX

Adds support for building multiple BVH types in order to support using both CPU and OptiX
devices for rendering simultaneously. Primitive packing for Embree and OptiX is now
standalone, so it only needs to be run once and can be shared between the two. Additionally,
BVH building was made a device call, so that each device backend can decide how to
perform the building. The multi-device for instance creates a special multi-BVH that holds
references to several sub-BVHs, one for each sub-device.
