Experimental: Remove Android PowerManager Wakelock dependence 

Helps clean up the deprecation of some of the methods used in the Android backend.
Other notes:
- No longer requires a special permission
- Platform now manages wakelock
- Google recommends using this instead of the previous method
Experimental: Remove Deprecated Wakelock Refrences from AndroidApplicationConfiguration

We use a new method now instead of PowerManager
