This commit adds nodes to do direct conversion between meshes and point clouds in geometry nodes. The conversion from mesh to points is helpful to instance once per face, or once per edge, which was previously only possibly with ugly work-arounds. Fields can be evaluated on the mesh to pass them to the points with the attribute capture node. The other conversion, point cloud to mesh vertices, is a bit less obvious, though it is still a common request from users. It's helpful for flexibility when passing data around, better visualization in the viewport (and in the future, cycles), and the simplicity of points. This is a step towards T91754, where point clouds are currently combined with meshes when outputing to the next modifier after geometry nodes. Since we're removing the implicit behavior for realizing instances, it feels natural to use an explicit node to convert points to vertices too.
