This PR adds stroke stabilization settings for the Sculpt mode lasso
tools:
* Mask
* Hide
* Trim
* Face Set
Only Sculpt tools have a user facing change, even though this was
implemented in `WM_gesture_lasso_modal` and related methods. Other
modes may choose to add these settings and toggles.
## Implementation
The implemented functionality is similar to the Annotate tool in both
interpolation of the new point and drawing the UI hint that
stabilization is happening.
The `radius` and `factor` properties have similar bounds as the same
Brush properties. All values are stored on a per-operator level, not on
a scene or otherwise global tool level.
