Add Word Per Minute calculation feature (#8054)

Browse source 
* Add Word Per Minute calculation feature

* Fix copyright info

* Remove header from quantum.c, setup overloadable keycode inclusion for WPM, update docs

* Simplify logic for keycode filtering

* Adding link from summary to wpm_feature info

* Update docs/feature_wpm.md

Typo in function prototype example in docs
