CrystalHD: Remove EXPERIMENTAL flag for known good formats.

With the flag in place, it's hard to actually use the decoder, and
I'm happy with how it works, with the exception of DivX3 where I've
never found a sample that worked that I was confident actually
matched what the hardware claimed to support.
