refactor: move default RGB/LED matrix #defines (#21938)

* refactor: move default RGB/LED matrix #defines

Moving the fallback definitions of macros like LED_MATRIX_VAL_STEP and
RGB_MATRIX_MAXIMUM_BRIGHTNESS to header files allows keyboards to
leverage these defaults without requiring #ifdef guards (and often
repeating said fallback definitions).

* style: use if(n)def for consistency

and remove redundant UINT8_MAX checks on maximum brightness

* refactor: remove INDICATOR_MAX_BRIGHTNESS macro
