Add Seed property to Fold and Simplex Noise Nodes, and reorganize other Noises for feature parity

[FoxyFox909]

Out of the 7 noise nodes that exist, there are two that are missing the Seed property:

• Fold Noise
• Simplex Noise

Additionally, for the noises that do have the Seed property, it is all over the place

For regular Noise (the non-coherent, fully random noise), the Seed property is under the Noise category. This is expected and reasonable.

For Fold Noise, the Seed property is not exposed.

For Strand Noise, the Seed property is at the very top, where it would be better put under the Noise category.

For Perlin Noise, the Seed is at the Output category, instead of Noise category.

For Simplex Noise, the Seed property is also not exposed.

For Cellular Noise, the Seed property is under the Noise category. Though it should probably be at the top so it is consistent with other Noises.

Fro Anisotropic Noise, the Seed property is at the top of the Noise category. A good place for the Property to be at.
