[Kernel] - Implemented SystemManagementController Class

- Added handling (partial or dummy) for SMC actions:
 - QUERY_TEMP_SENSOR, QUERY_TRAY, QUERY_AV_PACK, QUERY_SMC_VERSION, QUERY_IR_ADDRESS, QUERY_TILT_SENSOR
 - SET_FAN_SPEED_CPU, SET_FAN_SPEED_GPU, SET_DVD_TRAY, SET_IR_ADDRESS, SET_POWER_LED, SET_LEDS

- Stub HalOpenCloseODDTray, XamLoaderGetMediaInfo, XamLoaderGetMediaInfoEx
- Partially Implement HalSendSMCMessage
- Implement XamLoaderGetDvdTrayState
- HalOpenCloseODDTray is used by dash and HalSendSMCMessage can be used by custom dashboards
