Instead of calculating time deltas every time we want to check a
timeout, calculate the projected end ahead of time.

Instead of counting loops for the purpose of calculating acceleration, use
timers and steps instead. This means that we can now tune how often the mouse
moves (`speedDelay`), how much it moves when it does (`speed`), how fast
acceleration is (`accelSpeed`), and how often we accelerate (`accelDelay`).
By default, the movement speed is one, and there is no delay, while acceleration
has an 50ms delay, and a speed of one.
But all of these can be tuned at run-time: we can turn off acceleration
completely, or slow down the mouse considerably - the possibilities are almost
endless!

When acting on `moveIntent`, set up the direction first, and move the cursor
only once, instead of twice (once for each axis). This makes the movement even
smoother, and also saves us a few bytes of code.

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.
