For now, PointerRNA is made non-trivial by giving explicit default
values to its members.
Besides of BPY python binding code, the change is relatively trivial.
The main change (besides the creation/deletion part) is the replacement
of `memset` by zero-initialized assignment (using `{}`).
makesrna required changes are quite small too.
The big piece of this PR is the refactor of the BPY RNA code.
It essentially brings back allocation and deletion of the BPy_StructRNA,
BPy_Pointer etc. python objects into 'cannonical process', using `__new__`,
and `__init__` callbacks (and there matching CAPI functions).
Existing code was doing very low-level manipulations to create these
data, which is not really easy to understand, and AFAICT incompatible
with handling C++ data that needs to be constructed and destructed.
Unfortunately, similar change in destruction code (using `__del__` and
matching `tp_finalize` CAPI callback) is not possible, because of technical
low-level implementation details in CPython (see [1] for details).
`std::optional` pointer management is used to encapsulate PointerRNA
data. This allows to keep control on _when_ actual RNA creation is done,
and to have a safe destruction in `tp_dealloc` callbacks.
Note that a critical change in Blender's Python API will be that classes
inherinting from `bpy_struct` etc. will now have to properly call the
base class `__new__` and/or `__init__`if they define them.
Implements #122431.

This makes it so that the `Ctrl J` keybind will run the join operator.
As there are only 2 modes and the other one already has a keybind it does not make sense to open the menu.
This matches Blender 4.2.

This operator deals specifically with add-ons, using the term extensions
is misleading as it works for legacy (non-extension) add-ons and
extensions can also be themes.
So far asset browsers always sorted assets by name, which resulted in
barely related assets being placed together, and related assets being
scattered. This can make navigating assets tedious, and introduces a lot
of visual noise because of scattered preview image styles.
Related assets are typically put into common asset catalogs, and related
catalogs are typically organized close to each other in the catalog
hierarchy. This makes catalogs a better characteristic to sort by,
solving the mentioned issues.
For asset shelves sorting by catalogs was introduced in 471378c666. This
PR exposes this feature to the asset browser, by introducing a new
option to sort either by name or by catalog. The new default is sorting
by catalog. Within a single catalog, assets are still sorted alphabetically.

This fixes the issue by traversing the new data structure for actions.
* When a slot is assigned, the action is baked into the slot.
* if no slot is assigned, it creates a new slot and bakes into that. However since no slot was assigned, the animation will be static.

All sculpt and paint modes should have the brush selector asset shelf
popup in the tool settings header. For curves sculpt mode this was
missing. There's no good reason for this, probably just an oversight.
All sculpt and paint modes should bring up the brush selector asset
shelf popup on Shift+Spacebar. For grease pencil vertex paint mode the
shortcut was missing. I think it was added earlier, but only for the
grease pencil v2 keymap, the v3 one got merged later only.
Python wheels from extensions were not being removed after
install/uninstall in some cases - although installing an extension
afterwards that used wheels would recalculate deps & remove them.
- Installing an extension didn't include the extension in the
compatibility-cache, causing uninstalling not to remove deps.
- Uninstalling an extension wasn't re-calculating the deps,
leaving them as-is.
Always write the compatibility-cache after installing and uninstalling
so changes are detected & handled.
The issue was that the strokes were not using the `POLY` type and
needed to be tagged.
This adds a function `tag_positions_changed` on the `GreasePencilDrawing`
so that the high-level python API can tag the positions if
the `point.position` attibute is written to.
