Add support for editor::SwapSelectionEnds everywhere (emacs exchange-point-and-mark) (#23428)

Browse source 
Add `editor:: SwapSelectionEnds ` action which swaps the cursor location from the beginning/end of a given selection.
Renamed from `editor::ExchangeMark` to `editor::SwapSelectionEnds`.
Unbound by default, bound to `ctrl-x ctrl-x` in Emacs keymap.
