On iPhone, MSE is disabled by default.
It can be enabled using an experimental setting, however it is mostly non-functional
as the SourceBufferParserAVFObjC relies on AVStreamDataParser class which itself is non-functional.
So testing for the availability of this class isn't sufficient,
we need to test that the init method itself doesn't return nil.

No test, as currently all MSE tests are disabled on iOS, and enabling those is out of scope for this change.i
On other platforms, covered by existing tests.
