Subject: Enable bundling Qt in Android package in build system

For bundling Qt, we need two things:

1. We need to build a regular .jar file out of the Java files,
so that they can be built into the app package. Dexing the
classes first (i.e. compiling the JVM bytecode to Dalvik
bytecode) is required for loading the .jar file at run-time,
but cannot be used for building it into the app, so we need
two different paths.

2. We need to specify which extra files have to be bundled for
each module (this is primarily for plugins and imports). This
is because there is no static dependency on these files, so
it cannot be detected during deployment.

Task-number: QTBUG-30751
