Enable using lite protos for Android.

Lite is the new preferred proto runtime on Android, for two reasons:
- It lends itself to better proguard optimizing
- There is only one flavor, so there is no risk in including
  proto libraries with overlapping definitions that use different
  flavors

This CL adds a generate_nano argument to the proto_java_library build
rule. This argument is default false, so new proto libraries will use
lite by default. However, existing libraries will be migrated in a
follow-up CL, so this change sets generate_nano to true for those
libraries.

It also adds the android_library rule that contains the runtime
library for lite protos.

For an example conversion CL for a proto target, see:
