      Description

      There are multiple ways of checking if an opCtx is in a multi-document transaction. They're each slightly different in practice and we use them somewhat interchangeably. We should clarify the semantic differences between these three, make sure that any place that uses one is using the correct one, and make it clearer what to do in the future.

      Ways to check:

      1. inMultiDocumentTransaction
      2. seeing if the opCtx has a top level WUOW
      3. checking if the read concern on the opCtx is "snapshot"
