GN + Android: support standalone .dex.jar output of Android libraries.

GN + Android: support standalone .dex.jar output of Android libraries.

This patch allows to set .standalone_dex_path as a variable in the
android_library target. This puts all dependencies together with the
library code in one dex.jar file.

This is needed to produce bundles of Java code packaged as Mojo
applications on Android.

Hi Chris, Ben;

Does this look reasonable to you?

I can't convince me that it is better to have this option or another template,
so LGTM once you check that changing the py file doesn't break gyp.

I'm fine with this, lgtm.
