Property Search: Support heading labels

Property Search: Support checkboxes with no headings

Further changes will be needed to keep track of the labels added
for headings.

Add null check for dvert

Initial "Make Asset" operator

Accessible via the Outliner context menu (ID Data submenu).

The operator currently copies the data-block and creates empty asset data for
it. This will later contain all the meta-data to "give the data-block meaning".

Of course there are many TODOs and questions remaining. This is the first step
so I can work more on meta-data support.
I created some files and that I think make sense.

Rename get_object_deform_vert; add comments

`get_object_deform_vert` ? `get_poly_deform_group_name`

Edit comments, and the UI tooltip of the export option.

Fix T77984: Cycles OpenCL error rendering empty scene

EEVEE: Shadows: Remove 1 pixel padding to the cubemap

This avoid having a much higher memory footprint as the underlying texture
size allocated by the driver is likely to be much higher (rounded to next
Power of 2 or other alignement requirements).

Fix T67587 Overlay: WeightPaint color blends with background in wireframe mode

Fix this by rendering to the overlay framebuffer when using alpha blend
mode.

Cleanup: Add functions to check the first brush step and symmetry passes

This adds three functions to check the state of the stroke in the
StrokeCache, removing the references to first_time and
mirror_symmetry_pass from the code. This makes easier to understand what
each code path is doing inside of each tool.

Some tools were using mirror_symmetry_pass incorrectly, so this should
also fix unreported bugs with radial and tiling symmetry related to that.

GPencil: Fix unreported primitive color always set as Vertex Color

When drawing a primitive, the color was always assigned as vertex color, so it was impossible to change it in the material settings.

Now, the color is set to material color or vertex color as expected.

Fix T77780 Overlay: Weight colors are not in render in the right colorspace

This was just a missing conversion.
