[WebCodecs] Route interlaced H.264 content to the software decoder

None of our hardware decoders support interlaced decoding, so we
should route this content to the software decoder.

The wrinkle is that there's no information in the codec string
which would tell us that the content is interlaced. For AVC content
we can peek at the description, but for annex-b content we won't
know until the first decode() call.

Given how rare this content is, it's not worth holding all annex-b
configure() calls until the first decode().

As such, this fix only works for AVC formatted content, annex-b
content will continue to throw a decoding error; though I've
promoted the DVLOG to a DLOG to help identify this case more
quickly in the future.
