Subject: Macros (#1234)

* Macros WIP

`helix_term::compositor::Callback` changed to take a `&mut Context` as
a parameter for use by `play_macro`

* Default to `@` register for macros

* Import `KeyEvent`

* Special-case shift-tab -> backtab in `KeyEvent` conversion

* Move key recording to the compositor

* Add comment

* Add persistent display of macro recording status

When macro recording is active, the pending keys display will be shifted
3 characters left, and the register being recorded to will be displayed
between brackets — e.g., `[@]` — right of the pending keys display.

* Fix/add documentation---
