Use complete Java.Interop

Start using complete Java.Interop, ie. `Debug` and `Release`
configurations instead of `XAIntegrationDebug` and
`XAIntegrationRelease`.

Add Java.Interop java sources to the list of sources to build
mono.android.jar. This is needed for `ManagedPeer` and other classes
with java counterparts.

Few updates to distinguish between `Android.Runtime.JavaObject` and
`Java.Interop.JavaObject`.

Added System.Collections reference is for `List<JniSurfacedPeerInfo>`
return type in `AndroidValueManager`.
