HDR: Fix ForceInterpretHdrVideoAsSdrTest, and expand to all APIs.

Previously, this was limited to API 29. Expand this to all API versions.

Also, update the test to:
(1) skip based on SDR format input instead of HDR format input
(2) Check the exception message in order to disambiguate between the decoder tone
mapping error, and general video format support error.
