Remove pixel_format from VideoDecoderConfig it's mostly lies.

We almost never have a valid pixel format anymore, so many places just
hardcode it to I420 regardless of what's in the file. It's not used for
anything, so just go ahead and remove it from the VideoDecoderConfig.

What we do need is a signal about the presence of an alpha channel, so
just use that directly instead of guessing at it based on the format.
