Introduce TestVideoConfig class.

We have a lot of cases where we need some pre-canned VideoDecoderConfig for
testing purposes. In these tests, we only care about general categories of the
video configs (e.g. validity, config change and encryption) rather than details
like visible rect and extra data. The new TestVideoConfig class serves
this purpose.

TEST=Unittests still pass.
