Enable ability to pass the resource apk to Robolectric so that it can consume binary resources.

This functionality is guarded by a flag, --experimental_android_local_test_binary_resources whose default value is false. If the flag is set to true, Bazel will generate the .ap_ and add the path to the .ap_ to the test_config.properties file. Bazel will still generate and pass the raw resources to Robolectric in both cases and so the cue to Robolectric that binary resources should be used is the presence of the path to the .ap_ in the test_config.properties file.
