In meow-reverse, run C-x C-x instead of running exchange-point-and-mark directly.

- Add `meow--kbd-exchange-point-and-mark` with value "C-x C-x".
- Change `meow-reverse` to run this macro via `meow--execute-kbd-macro`.

This change supports using `rectangle-exchange-point-and-mark` (`C-x C-x`) in
`rectangle-mark-mode`.
