Subdivision level navigation

This is an operator for "navigating" between subdivision levels of Multires / Subsurf / Subdivide modifiers on selected objects (Blender has a similar operator called "Subdivision Set", but with fewer options).

If you want to make a shortcut for it, use the mouselook_navigation.subdivision_navigate operator identifier.

Warning: if you use Blender versions earlier than 2.93, you may encounter problems when trying to undo the effects of this operator in Sculpt mode.

Level - the target subdivision level (if Relative is off) or subdivision level offset (if Relative is on)
Relative - whether to set a specific subdivision level or to increment/decrement it
Auto subdivide - automatically subdivide when necessary; also adds a subdivision modifier if the object has none (Multiresolution for Mesh objects in Sculpt mode, Subdivide for Grease Pencil objects, Subdivision Surface in other cases)
Remove higher levels - if level is decremented, remove all higher levels
Subdivision method - which method to use for subdividing
Show dialog (keymap-only option) - whether to show the dialog with options or to execute the operator immediately

Known Issues

The "Blender" trackball mode doesn't actually behave like in Blender
- Ortho-grid/quad-view-clip/projection-name display is not updated
- Blender's Rotate Around Selection behavior is not exactly replicated in sculpt/paint modes and when editing text-curves
- Zooming/rotation around the last paint/sculpt stroke position is not supported
- Panning is not possible when view is locked to 3D cursor (Blender does not provide a way to control this offset)
