Fix T92099: No undo when moving viewport with camera locked to view

Supports undo step generation while navigating in locked camera view.
NDOF & track-pad navigation are not included for now.

Actions that uses smooth view can be supported but are outside
the scope of this change, includes undo push for:

- VIEW3D_OT_view_pan
- VIEW3D_OT_dolly
- VIEW3D_OT_fly
- VIEW3D_OT_move
- VIEW3D_OT_rotate
- VIEW3D_OT_walk
- VIEW3D_OT_zoom
