feat: Parameterised Mod Morph and Tap Dance

[Nick-Munnich]

General idea is to have a binding-params array property which maps parameters input to the behavior to the behaviors found in the bindings array. Bit flags and some macros to tidy it all up.

Docs are included, I decided to substitute the references to the non-parameterised version with the parameterised one in the interest of "one way to do it". Current one was moved to a footnote.

In general I think the approach and user experience side of things is good. May add more tests. Unsure whether documentation needs further reworking or if the non-parameterised version should remain prominent.

PR check-list

• Branch has a clean commit history
• Additional tests are included, if changing behaviors/core code that is testable.
• Proper Copyright + License headers added to applicable files (Generally, we stick to "The ZMK Contributors" for copyrights to help avoid churn when files get edited)
• Pre-commit used to check formatting of files, commit messages, etc.
