Anne Pro 2 Refactor (#16864)

* move RGB Matrix rules to keyboard level

* move PERMISSIVE_HOLD config to keyboard level

* annepro2.c: convert tabs to spaces

* refactor rules.mk files

Reformats each version's `rules.mk` file to be arranged more similarly to those of the rest of the keyboards in QMK.

No logic change.

* annepro2.c: allow compilation without RGB Matrix

Wraps the `led_enabled` definition and the `KC_AP_RGB_*` keycodes in `#ifdef RGB_MATRIX_ENABLE`, allowing successful compilation if the user sets `RGB_MATRIX_ENABLE = no`.

* rework readme files

Reworks the main `readme.md` file to be more friendly to GitHub viewing, and removes the single-line version-specific readme files (exposes the main readme to QMK Configurator users).

* info.json: update maintainer value

* info.json: apply friendly formatting
