refactor(behaviors): Giving global-quick-tap its own term

Detaching the global-quick-tap functionality from the quick-tap term.
This makes way for two improvements:

1. This functionality can be added to combos under a unified name
   'global-quick-tap-ms'.

2. This allows users to set a lower term for the 'global-quick-tap'
   (typically ~100ms), and a higher term for the regular
   quick-tap (typically ~200ms)

This deprecates the global-quick-tap option, however if it is set, the
quick-tap-ms value will be copied to global-quick-tap-ms.
