Remove the "_for_read" suffix from methods to get geometry and geometry components. That should be considered the default, so the suffix just adds unnecessary text. This is consistent with the attribute API and various implicit sharing data access methods. Use "from_mesh" instead of "create_with_mesh". This is consistent with the recently used naming for the `IndexMask` API. Pull Request: https://projects.blender.org/blender/blender/pulls/110738
