[NFC] Refactor LocalGraph's core getSets API (#6877)

Before we just had a map that people would access with localGraph.getSetses[get],
while now it is a call localGraph.getSets(get), which more nicely hides the internal
implementation details.

Also rename getSetses => getSetsMap.

This will allow a later PR to optimize the internals of this API.

This is performance-neutral as far as I can measure. (We do replace a direct read
from a data structure with a call, but the call is in a header and should always get
inlined.)
