Build Tasks to Find and Verify TransportVersion Definitions

[JVerwolf]

This PR introduces a set of build tasks to find and verify TransportVersion definitions using the new model.

This includes:

1. A task to locate all transport version declarations of the form TransportVersion.fromName("some_name");, and record all the String literal arguments in a build file.
2. A task to verify that all TransportVersion declarations have a corresponding data file
3. A task to verify that all TransportVersion data files have a corresponding declaration
4. A task to produce a manifest file that contains the filenames of all data files, for later use in a getResources call.

A subsequent PR will introduce a task to generate the data files.
