Subject: [IR] Inroduce ModuleToSummariesForIndexTy (NFC) (#105906)

This patch introduces type alias ModuleToSummariesForIndexTy.

I'm planning to change the type slightly to allow heterogeneous lookup
(that is, std::map<K, V, std::less<>>) in a subsequent patch.  The
problem is that changing the type affects many places.  Using a type
alias reduces the impact.
