If this must match, shouldn't we leave the literals?

I think that's redundant. Values in this enum must match media::VideoProfile,
but AFAIK there's no direct requirement for the values here to remain unchanged,
since they are not logged into UMA. So I think it's sufficient to have just
static asserts for ensuring values match the media::VideoProfile and have a
single source of truth in media::VideoProfile with explicitly specified values.
