Make `PREVENT_STUCK_MODIFIERS` the default (#3107)

* Remove chording as it is not documented, not used, and needs work. * Make Leader Key an optional feature. * Switch from `PREVENT_STUCK_MODIFIERS` to `STRICT_LAYER_RELEASE` * Remove `#define PREVENT_STUCK_MODIFIERS` from keymaps.

 As you can see, you have a few function. You can use `SEQ_ONE_KEY` for single-key sequences (Leader followed by just one key), and `SEQ_TWO_KEYS`, `SEQ_THREE_KEYS` up to `SEQ_FIVE_KEYS` for longer sequences.
 
 Each of these accepts one or more keycodes as arguments. This is an important point: You can use keycodes from **any layer on your keyboard**. That layer would need to be active for the leader macro to fire, obviously.

 ##### Process Record

 The `process_record()` function itself is deceptively simple, but hidden within is a gateway to overriding functionality at various levels of QMK.

Depending on options set in rule.mk or elsewhere, only a subset of the functions below will be included in final firmware.
