Computes the merged type of two ApiContract objects.
Groups that only exist in A are kept as-is.
Groups that only exist in B are kept as-is.
Groups whose key appears in bothA and B have their endpoint maps
intersected (A[K] & B[K]), making all endpoints from both sources
visible on the merged group.
