More header include fixes

MapVector started querying for constructability of stored types with
templates. As such, we need the definition of `LocalTypeDataKey` so that
it can instantiate the template.

We also lost a transitive include of `TinyPtrVector`, which we use, so
including it in `ConformanceLookupTable.h`.
