Attributes are unifying around a name-based API, and we would like to be able to move away from CustomData in the future. This patch moves the identification of active and fallback (render) color attributes to strings on the mesh from flags on CustomDataLayer. This also removes some ugliness used to retrieve these attributes and maintain the active status. The design is described more here: T98366 The patch keeps forward compatibility working until 4.0 with the same method as the mesh struct of array refactors (T95965). The strings are allowed to not correspond to an attribute, to allow setting the active/default attribute independently of actually filling its data. When applying a modifier, if the strings don't match an attribute, they will be removed. The realize instances / join node and join operator take the names from the first / active input mesh. While other heuristics may be helpful (and could be a future improvement), just using the first is simple and predictable. Differential Revision: https://developer.blender.org/D15169
