Use Key API in indexes

Summary:
- Only in TypeIndex, not in Index (since we might want to store something other than identifiers as values)
- We might want to do the same in the `SynchronizerStore` for localId ↔ remoteId indexes

Depends on D13735

Some quick benchmarks (against develop and D13735): {F6022279}
