Add standard definitions for ALGR and KC_ALGR (#4389)

* Add standard ALGR defition, remove (re)definitions from language files

* Use ALGR(kc) consistently in ALTGR(kc) aliases

* Non-Nordic keymaps should not use NO_ALGR

* Add standard KC_ALGR definition

* Update docs with ALGR and KC_ALGR

* Update SS_ALGR and ALGR_T aliases
