refactor: modular RGB effect registration API

Browse source 
Replace hardcoded effect enum/switch-case with STRUCT_SECTION_ITERABLE
registration. Effects register via ZMK_RGB_EFFECT_DEFINE macro.

Core API (rgb_effect.h):
- zmk_rgb_effect_ctx passed to render callbacks
- zmk_rgb_request_refresh() for static effects
- ZMK_RGB_EFFECT_STATIC flag skips animation timer
- on_select/on_deselect lifecycle hooks
- zmk_rgb_hsb_to_rgb/scale helpers now public

Built-in effects (solid/breathe/spectrum/swirl) use same API.
Per-key layer RGB, behaviors, DTS bindings extracted to external
zmk-rgb-effects module.
