Vim: Add emacs mapping to command mode (ex)
Vim: Add emacs mapping to command mode (ex)

Note: because we’re mapping ESC, vim will wait for another command to
be typed when we type <ESC> in the command mode.

This will be addressed in a later commit with the fast-keycodes hack

We need to use <ESC>? instead of <A-?> because the term was configured
to send the +Esc escape sequence for alt/option
