This adds the types * `IndGroupInfo`, a variant of `InductiveVal` with information that applies to a whole group of mutual inductives and * `IndGroupInst` which extends `IndGroupInfo` with levels and parameters to indicate a instantiation of the group. One purpose of this abstraction is to make it clear when a fuction operates on a group as a whole, rather than a specific inductive within the group. This is extracted from #4718 and #4733 to reduce PR size and improve bisectability.
