Add emacs keybindings for mark emulation (#22904)

Browse source 
These keybindings extend the already selected text. This allows closer
emacs emulation where subsequent movement commands extend / shrink the
current selection instead of dismissing it.

This is a follow up on 
- #21927

Release Notes:

- Added emacs movement keybindings that extend/shrink the current
selection
