Enable test packages to be made wholly or partially hermetic through use
of "fuchsia.test" facets in their package manifests.

- Remove the unused //build/fuchsia/exe_runner.py script.
- Rename run_package.py to run_test_package.py, and similarly for the
  methods and types it publishes.
- Update the RunTestPackage() API to support launching the component
  using the 'run_test_component' command, rather than 'run', if
  requested.
