Implement NullVideoDecoder to avoid crash on unsupported decoders.
There is a use case with external codec factories that only support
encoding but not decoding for a given type. This leads to a crash
due to null being registered as codec (after a DCHECK).
This CL adds a NullVideoDecoder that is used instead of the null to
not crash but log to LS_ERROR.
