feat: add support for RAK3312 (New RAKwireless wiscore ESP32-S3 + SX1262) (#7115)

* Add support for RAK3112 variant with necessary configurations and definitions

* Add the configuration of the LED pin

* Refactor rak3112 variant configuration: update name, remove unused files,

* Update RAK3112 configuration: refine memory settings,  adjust GPS pin definitions

* Update RAK3112 hardware vendor definition to use correct model

* configure LED pins and update module definitions

* Update USB mode configuration for RAK3112 board

* Update power and battery configuration in rak3112 variant

* Cancel the modification of mesh.pb.h

* Rename RAKwireless RAK3112 to RAK3312
