misc/androidstudio: add support for the android gradle plugin

The gobind plugin exposes a set of Go packages as a AAR file ready to be
used by and Android project. Unfortunately, being a library project
limits the Go packages to access only the Java API from the standard
library and the Android SDK.

This CL tightens the integration with the Android plugin to support access
to project dependencies such as the Android Support Library, to the generated
R.* resource classes and finally to the Android databinding classes.

When the gradle project has loaded the Android plugin, the generation of
the Go library is split in two.
First, the gobind tool generates the Java classes for the bound Go
packages. In this step, Go packages can access the standard Java and Android
libraries as well as project dependencies. After this step, Android
databinding layout files can refer to Go classes.
In step two, the gomobile tool generates the JNI libraries
with the Go implementation of the generated Java classes. In this
step, Go can access the standard Java and Android libraries,
dependencies as well as R.* and generated databinding classes.
