rtlwifi: btcoex: Add common function for qeurying BT information

This commit implement the common function to sort old features, and add
more new features that are get_supported_feature, get_supported_version,
get_ant_det_val, ble_scan_type, ble_scan_para, bt_dev_info,
forbidden_slot_val, afh_map and etc.
