Cleaning up NvCloth gem. Removed any reference to LmbrCentral and legacy renderer since now it uses Atom. (#154)

- Removed any usage of LmbCentral and legacy renderer from NvCloth gem.
- Cloth rule can only be added to Mesh groups, not allowed in Actor groups anymore.
- Removed ActorAssetHelper since actors now share the mesh model format and therefore they also use MeshAssetHelper.
- Updated NvCloth gem.json file with the fields from the template.
- Updated cloth chicken asset to not convert axis.
