Implements the design from #120318. The existing selection nodes now have the ability to deal with float/soft selection. For meshes the soft selection corresponds to the inverse of the sculpt mask attribute. In the future this will likely be unified with edit mode selection a bit more which is why this design was chosen compared to separating masking and selection. Curves and point clouds already use a single selection attribute with either data type. Pull Request: https://projects.blender.org/blender/blender/pulls/126316
