Surface Mesh Segmentation Using Region Growing

[danston]

This PR is a draft version of the planar decimation feature from PMP using Region Growing when segmenting an input mesh. We use Region Growing first to detect planar shapes. We then exploit these shapes to build a graph of polylines on the mesh and apply Region Growing again on top of this graph in order to detect linear regions. When we know all linear regions, we can easily detect unique corners of the mesh.

This PR depends on PR #5563 and PR #5461.

We decided not to add a new API to the segmentation package.
