Store bevel weights in two new named float attributes: - `bevel_weight_vert` - `bevel_weight_edge` These attributes are naming conventions. Blender doesn't enforce their data type or domain at all, but some editing features and modifiers use the hard-coded name. Eventually those tools should become more generic, but this is a simple change to allow more flexibility in the meantime. The largest user-visible changes are that the attributes populate the attribute list, and are propagated by geometry nodes. The method of removing this data is now the attribute list as well. This is a breaking change. Forward compatibility is not preserved, and the vertex and edge `bevel_weight` properties are removed. Python API users are expected to use the attribute API to get and set the values. Fixes #106949 Pull Request: blender/blender#108023
