[android]: Force app to use the displays max set refresh rate

Browse Source 
Since Android 15, google automatically forces "games" to be 60 hrz. This ensures the display's max refresh rate is actually used. Tested on a Google Pixel 7 Pro with Android 16

Emulation Activity was excluded for battery usage concerns
