Velocikey: Match RGB animation speed to typing speed (#3754)

* Draft commit of typing speed RGB control

* More information in the readme

* Support all RGB animation modes (Fixes #1)

* Added support for all RGB light modes to use typing speed

Except christmas lights because that is seizure-inducing at high speeds!

* Introduced a value range specific to each RGB mode

Because some modes are a little too much when running at full speed!

* Update readme.md

* Update readme.md

* Re-arrange typing_speed definitions (Fixes #5) (#6)

* Re-arrange variable definitions to avoid including quantum.h from rgblight.c

* Fix a compilation error when trying to run make test:all

* Tweaks to the typing speed decay rate

* Renamed to momentum; moved implementation into dedicated files

* Groundwork for toggling momentum on/off (currently always on)

* Add EEPROM toggle for momentum-matching

* Moved momentum out of RGBLIGHT_ENABLE toggles so it's more generic

* Move momentum decay task out of rgblight_task()

* Fix missing momentum.h in lufa.c

* Experimental LED support (untested)

* Update feature documentation

* Revert "Merge branch 'led-support' into master"

This reverts commit e123ff5febf61639b9a9020748e1c2e2313460ff, reversing
changes made to df111a55b9d4929182e16108b1c0ead15b16df97.

* Move velocikey EECONFIG definition to depend on VELOCIKEY_ENABLE

* Rename decay_task function to decelerate

* Apply suggestions from code review

Co-Authored-By: chrislewisdev <chris@chrislewisdev.com>

* Re-order eeconfig definitions

* Apply coding conventions

* Apply #ifdef check in lufa.c

* Refactored interval time checks into one functionc

* Small rename

* Fix unused function error for layouts not using all rgb effects

* Only update EEPROM if Velocikey is enabled

* Incorporate code review feedback

* Small adjustment to top-end decay rate

* Add Velocikey documentation to table of contents

* Bring tetris:default keymap size down by disabling audio
