Add is unique in migration v2 + refactor inferDeletionFromMissingEntities (#15070)

## Goal
- inferDeletionFromMissingEntities is now a map instead of a single
bool, allowing us to parameterise it based on the entity we want to
compare
- Adding index creation/update when field isUnique is set to true and
index deletion when isUnique is false (for now)
