Subject: UI: Improve Modifier Panel Header Menu

This makes a few changes to the modifier panel header:
  1. Adds "move to top" and "move to bottom" buttons.
  2. Adds a checkmark icon for "apply"
  3. Makes it narrower, the text is closer to the dropdown icon.
     (Requires the change in ui_block_func_POPUP)
