perf(wm): reduce border jank on ws switch

Browse Source 
This commit introduces a few changes to reduce border jank, especially
when switching workspaces:

- The border is hidden before the windows start to reorganize when a
  workspace switching command is received instead of after
- Avoid unncessary window.focus() call when switching workspace
- Use WindowManager.focused_window() instead of the window received from
  the WindowManagerEvent when updating or setting the active border
  position as it more accurately matches user expectations when
  switching back to a workspace to find the focused window being the one
  that you left when you switched away
