eshell: Setup some helper functions in eshell-additions, move bindings to there.

- A helper function to instantly perform commands
- eshell-goto-latest-prompt to remove any artifacts when performing
  these instant commands

Bindings needed to be moved over to that section cos they utilise
these helpers.
