Update element/typefind factory ranks

The only None ranks now are:
- cdgdec/cdgparse: Primary
- rav1enc: Primary
- reqwesthttpsrc: Marginal
- s3sink/s3src: Primary
- mccenc/mccparse: Primary
- sccenc/sccparse: Primary

All other ranks are set to None until the elements are ready to replace
the existing C elements, or are otherwise production-ready and of a
element kind that should be autoplugged in one way or another.

For example the sodium elements are production-ready but can't be
autoplugged and as such should stay at a None rank.
