rHGf970cca30989: merge: use collections.defaultdict() for mergeresult.commitinfo

Summary

We will be storing info from mergeresult.commitinfo to mergestate._stateextras
in upcoming patches, let's make them use same structure so that we don't have to
make much efforts in transferring info from one to other.

pulkit added a child revision: D8922: merge: introduce `addcommitinfo()` on mergeresult object.Aug 10 2020, 7:18 AM

Having a filenode key that does not contains a filenode is quite misleading. Can we use a different key ? (and align the extrastate dict in the same direction?)
