[Android] Support arguments from Activity Monitor.

Activity Monitor can start activities by using adb to invoke it.
This will allow us to set the user directory and autostart file from adb.

adb shell am start -n org.dolphinemu.dolphinemu/.gamelist.GameListActivity -e AutoStartFile /sdcard/AC.gcz -e UserDir /sdcard/dolphin-emu2/

This allows more automated testing to be done with Dolphin on Android.
