      Description

      This will be essentially undoing SERVER-57758 – we will need to:

      • Rename the internalQueryEnableSlotBasedExecutionEngine back to something like internalQueryForceClassicEngine, so that its sense is to disable SBE and force the use of the classic engine. The default value will be false.
      • Change any existing SBE-on tasks in all Server and Query patch configurations such that they are "SBE-off", and test the classic engine.
