tap-dance: Support user_data for the callbacks

Browse Source 
Refactored the code a little, so all callbacks now receive a `user_data`
pointer, which can be anything. As an example, the key pairs from
`ACTION_TAP_DANCE_DOUBLE` now use this, and custom, built-in functions.

This makes it easier to extend the tap dance functionality, and also
simplifies the code a little.
