quantum/debounce: rename debouncing algorithms (#9564)0.10.7
* quantum/debounce: rename debouncing algorithms according to Issue 8763
This is the second attempt at implementation, with no ts_ and cy_ prefixes, since those will be implemented with macros.
* Debouncing documentation: Refactor, add some generic info, and merge into a single document
