Bug17281 - Retain momentary layers until the end of tapping (#17282)

Browse source 
* Make process_tapping more readable

Move most #ifdefs into conditionally defined macros to make the logic
easier to follow.

* Retain momentary layers until the end of tapping

This allows mod-tap and layer-tap keys on layers to behave as expected.

Bug: https://github.com/qmk/qmk_firmware/issues/17281

* Add tests for delayed mod/layer release while tapping

Mods and layer key release is delayed while tapping is in progress to
ensure that the tap is registered with the modifier state and on the
layer where the key was first pressed.
