76e243ce - [pmo] Allow for the AvailableValueAggregator to know if it is being used to Borrow, Copy, Take.

[pmo] Allow for the AvailableValueAggregator to know if it is being used to Borrow, Copy, Take. Previously, we only specified via a boolean value whether or not we were a take or not. Now we have an enum which is more specific and descriptive. It will also let me fix an issue that occurs with Borrow/Copy incrementally as separate patches.
