The default value for `FLOAT_COLOR` attributes is white. We can't
change this default easily.
This fix will initialize the attributes accessed through the high-level
python API with their expected default value. In the case of
vertex colors, this is fully transparent black.

Example:
Step is 3
Action starts at 1, so the action will try to export frames 1 / 4 / 7 / 10, etc...
But full object backing is enable, and scene starts at 0.
So cached data are on frame 0 / 3 / 6 / 9 / 12, etc...
When we are trying to export the action on armature after the full bake on empty, we are trying to retrieve frame 1, but cache was on 0 / 3 / 6 / 9
error log will go to stderr, and others to stdout
A new parameter in operator to set the loglevel from command line bpy.ops.export_scene.gltf(loglevel=logging.INFO)
If not set from the ops, value is -1, and is set, as before, from the bpy.app.debug_value
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.
