In some situations, layers were filled with their default value when converting from Mesh to BMesh (entering edit mode, for example). This was caused by the recently added "copy mesh to bmesh" or "merge mesh to bmesh" custom data functions creating a difference custom data format than was used for the copying functions used later. `CustomData_to_bmesh_block` is not robust enough to handle simple differences in layout between the layout of the source and result CustomData layers, because it relies on the order of the types and the number of layers within each type. As a fix, make the "mesh to bmesh" special case more explicit in the conversion functions. This makes the difference in the API smaller, which is a nice improvement anwyay. Fixes T101796
