Move the hooks inside the `MouseKeys_` object, and drop the
`handle_mouse_key_event` function, by inlining it into the event handler hook.

Instead of calculating separate acceleration for the x and y axes, use only a
single one, that applies to both axes. Thus, holding mouse up, and then pressing
and holding right will move the mouse cursor in a straight diagonal line,
instead of a curve.

Instead of acting on mouse movement keys immediately in the event handler hook,
just store them, and act on them during a loop hook. This has the effect of
collecting all movement intents noticed in a full scan, and acting on them in
one go, rather than acting individually.
This makes diagonal movement (up & right keys pressed at the same time) a lot
smoother, at the cost of a few ms of delay. The delay is not noticeable, and the
smoothing would be a good trade anyway. No more jerky diagonal movements!

This is the same Keyboardio-MouseKeys that lived in core KeyboardioFirmware up
until this point. It has been lifted out, the same GPL-2 license file added,
along with a README, and the URL in library.properties has been updated.
