fix(nt/bluedroid): Split the device name set functions feat(bt/bluedroid): added APIs to get/set device name on BT GAP side change(bt/common): Marked some APIs in device module as deprecated 1. esp_bt_dev_set_device_name 2. esp_bt_dev_get_device_name change(bt/bluedroid): use BT GAP APIs to set/get device name in bluetooth classic examples change(bt/bluedroid): use BT/BLE GAP APIs to set/get device name in coexist examples
