Only use GOOGLE_TV constants for Android <14

[ius]

Chromecast (HD) with Android 14 currently fails to return current_app correctly. See home-assistant/core#153778.

The 'Chromecast only' special cased command constants prevent the code path from reaching the (working) Android 13/14 constants. Fixed it by relying on the generic constants for Android 14.

Tested using:

#!/usr/bin/env python3
from androidtv.androidtv.androidtv_sync import AndroidTVSync

atv = AndroidTVSync("192.168.0.29", 5555, "/home/user/.android/adbkey")
atv.adb_connect()
atv.get_device_properties()

print("current_app:", atv.current_app())
print(atv.update())
