Add GET_TAPPING_TERM macro to reduce duplicate code (#16681)

* Add GET_TAPPING_TERM macro to reduce duplicate code

The macro gives the right tapping term depending on whether per-key
tapping terms and/or dynamic tapping terms are enabled. Unnecessary
function calls and variable resolution are avoided.

Fixes #16472.

* Use GET_TAPPING_TERM for Cirque trackpads
