Enhance git symbol quick pick handlers with token count estimation and direct text insertion

- next to 'diff with commit message' show token count
- when going back from 'commit reference options' we should have last selected item highlighted
- escape key from 'commit reference options' doesn't show a list of commits but 'symbols'. Make sure escape key works like 'go back' action from the titlebar
- the token count on 'commit reference options' is different than it is while using symbol replacement
- once a commit is accepted and placed, show list of commits again so the user can select another one
- don't append 'tokens' in descriptions
- considering 'changes' symbol, in multi root folder workspaces, should first ask for root-folder selection
- when placing 'changes' symbol, show token count next to branches
- should not show the temporary 'calculating...' text
