tests: Add tests for grl_data_*_for_id()

Basic tests to handle API that was recently introduced to the
following cases:

- When a metadata-key does not exist and shall be created by this API
  with GType based on GValue (parameter). This test checks all
  supported GTypes by those APIs.

- When the metadata-key exists, so it sets or adds the GValue
  to it.
