more Basic Mesh support for most components

[anatawa12]

Avatar Optimizer generally doesn't support basic Mesh Renderer, but many components should have better experience with basic Mesh support.

MeshInfo2 itself does support Basic Mesh renderer.
Therefore, we don't have to do big rewrite.

MeshInfo2Holder system does not have basic mesh support for now so we have to add.

Considerations

Some components should not duplicate Mesh instance for each basic mesh renderer; we should use same across avatar.
But some other components should duplicate mesh for each renderer.

ToDuplicate: RemoveMesh components
Not to duplicate: Optimize Texture

If we implemented to not duplicate basic mesh, we have to support single MeshInfo2 multiple Renderer for bone-less meshes
