feat: add blur_lockscreen option to apply blur to lock surfaces

Browse source 
Adds a new `blur_lockscreen` config option (default: 1) that, when
enabled alongside the existing `blur` option, applies scenefx blur
to wlr-session-lock surfaces on each commit.

Implementation adds:
- `commit_lock_surface` listener and `lock_scene_tree` pointer to
  the Monitor struct
- `commitlocksurface` handler that calls iter_layer_scene_buffers
  on the lock scene tree
- Cleanup of both fields in destroylocksurface
