Surfaces API: add updated open simplex noise generators by K.jpg.

* Uprev to 7.0.0-alpha.2
- Deprecate OpenSimplexNoise (not for removal)
- Add OpenSimplexNoise2 (K.jpg's OpenSimplex2(F)
- Add OpenSimplexNoise2S (K.jpg's OpenSimplex2S
- Instances w/ seed and utility generate() methods added to new noises
