As described in T95966, the goal is to move to a "struct of arrays" approach rather than gathering an arbitrary set of data in hard-coded structs. This has performance benefits, but also code complexity benefits (this patch removes plenty of code, though the boilerplate for the new operators outweighs that here). To mirror the internal change, the options for storing mesh bevel weights are converted into operators that add or remove the layer, like for some other layers. The most complex change is to the solidify modifier, where bevel weights had special handling. Other than that, most changes are removing clearing of the weights, boilerplate for the add/remove operators, and removing the manual transfer of bevel weights in bmesh - mesh conversion. Eventually bevel weights can become a fully generic attribute, but for now this patch aims to avoid most functional changes. Bevel weights are still written and read from the mesh in the old way, so neither forward nor backward compatibility are affected. As described in T95965, writing in the old format will be done until 4.0. Differential Revision: https://developer.blender.org/D14077
