BBS Port: Mesh Subdivision (#12150)

Browse Source 
Ported from BBS
You can now right-click a part and choose Subdivide Part to apply Loop subdivision with multiple iterations. This is useful for models with low original mesh resolution.

> [!NOTE]
> 1. Only meshes without non-manifold edges are supported.
> 2. Color attributes will be lost after subdivision. We recommend subdividing first, then painting and applying colors.

Not perfect and it can break some features but a nice to have and we can improve it.

Best case scenario a sphere:
Each picture is a Mesh subdivision step over the other
