Subject: rgblight.c: add  remap feature (#5243)

* rgblight.c: add RGBLIGHT_LED_MAP support

* add code to keyboards/helix/rev2/keymaps/five_rows/config.h to test rgblight.c:RGBLIGHT_LED_MAP

* Test end. Revert "add code to keyboards/helix/rev2/keymaps/five_rows/config.h to test rgblight.c:RGBLIGHT_LED_MAP"

This reverts commit e7488d6f7338460b533d7d19a09deccb011000bf.

* update docs/feature_rgblight.md

* led_map[] move to PROGMEM
