feature(hold-tap): no-hold-flash for retro taps

Browse source 
This is an improvement on retro-tap, solving the 'flashing hold' issue
users people experience.

When the tapping-term expires, the hold key is normally pressed. When
retro-tap is enabled, this is undesirable; only an interrupted hold-tap
should trigger the hold behavior.

This change disables the hold behavior for the 'STATUS_HOLD_TIMER'
state when retro-tap is enabled, and makes sure the
'STATUS_HOLD_INTERRUPT' state will be triggered when appropriate.

If retro tap is enabled, the tap behavior is triggered when releasing the hold-tap key if no other key was pressed in the meantime.
For example, if you press `&mt LEFT_SHIFT A` for a long time and then release it without pressing another key in the meantime, it will output `a`. (Actually, `LEFT_SHIFT` will be pressed when the tapping term expires, which is released just before the `a` is tapped.
