Add step sequencer feature (#9703)

Browse source 
* sequencer: create togglable feature

* sequencer: add support for steps

* sequencer: add support for tempo and resolutions

* sequencer: schedule a message print at the right frequency

* sequencer: send a hardcoded note

* sequencer: add support for 8 tracks

* sequencer: play several notes simultaneously

* sequencer: only play the active tracks for a given step

* sequencer: change the default behavior of the track toggler

* sequencer: make number of tracks and track notes customizable

* sequencer: move the keycodes down

Not adding them at the end of the list apparently risks breaking
compatibility with VIA.

* sequencer: add unit tests

* sequencer: add unit test for matrix_scan_sequencer

* sequencer: expose internal state for better unit-testability
