feat: Action improvements (#472)

* feat: replace_map

* feat: Add action_set and action_state

* fix: Move all actions.get_ to action_state.get_

* fix: replace all internal references of _goto_file_selection_edit

* feat: add some docs

* fix: lint

* feat: actions.select

* remove mentions and usage of goto_file_selection APIs

* feat: special case attach_mappings to be overridable and defaultable

* Having goto_file_selection mappings will cause a error

as well as replacing deprecated goto_file_selection methodes

For config and replacing use this instead:
- actions.select_default
- actions.select_horizonal
- actions.select_vertical
- actions.select_tab

Only replacing:
- actions.set.edit -- for replacing all select functions

* adds actions.state.select_key_to_edit_key
