app: android activity lifecycle awareness

This CL fixes two bugs in the existing app implementation on android.
The first, is it assumed a single NativeActivity instance is created
per process. This is not true. If you open an app, hit the back
button, then open it again, the original activity is destroyed and a
new one is created. So only call main.main in the first onCreate.

The second bug has to do with window lifetimes. Previously we only
processed GL work while the window existed, as part of a paint cycle.
This missed GL events called as part of a lifecycle downgrade when
the window was destroyed. (I.e. the contents of onStop.) This CL
fixes this by making the main android event processing loop last for
the life of the process, not the window.

Fixes golang/go#11804.
