Bone Overlay: support bone wireframe opacity settings.

When weight painting the bone overlay is extremely intrusive,
effectively requiring either extensive use of hiding individual
bones, or disabling the whole bone overlay between selections.

This addresses the issue by adding two bone opacity sliders that
are used for the 'wireframe' armature drawing mode. One directly
controls the opacity in a uniform way. The other one allows fade
based on the depth between the near and far clip planes in order
to provide an automatic visual cue about which bones are closest.

API Docs: CSS: Fix long enum list

This commit makes some adjustments to a previous fix which broke with
new versions of sphinx/theme.

Fixes T76453

Update RNA to manual url mappings

Fix Unreported: Run time error in UI code

Steps to reproduce:

1. Add clip to clip editor
2. Open the tracking settings & tracking settings extra panels

To fix this the sub panel is only drawn if a track is active.
The main panel will exit early and display a "No active track" message.
This is consistent with other panels in the clip editor.

Cleanup: Explicitly pass icon size to generation function, not just bool

* This way you don't have to look up the function declaration to know what the
boolean value means.
* You can call the function in a loop over the available sizes and pass the
index as size.
* Makes it easier to add a new size in future if needed.

Sculpt: Update clay strips presets with custom input curves

Fix multiple crashes with custom input curves

Fix T84024: Empty image opacity labeled transparency

This value really is the opacity, or the alpha, since a value of 1.0 means
that the image is fully visible, not invisible like "full transparency"
would suggest. Mistake in rBea4d28aea0343a.
