Good to see the isEmpty check arrive too!

Please also state the restriction in the opposite direction, using the same "At this time..." wording.

Description
This change makes it possible, when creating an issuer, to decline to use recover sets. It also converts priceAuthority and fluxAggregator to do so. This only affects new instances of these contracts. The existing instances hold large numbers of old no-longer-used quote-payments which are currently uncollectible.
This PR was based on #8498 (itself based on #8418) which would have gradually removed quote-payments from the recoverySet. We aren't taking that approach because those vats are not upgradeable. #8418 would have released all the unneeded quote-payments at once, which would likely have overwhelmed the GC system.
#8400 talks about the general problem. #8928 talks about one possible long-term fix cleaning up the retained garbage.
Security Considerations
N/A
Scaling Considerations
It's all about reducing the impact of large quantities of unneeded quotes. This PR will stop us from accumulating more quotes.
Documentation Considerations
N/A
Testing Considerations
We will validate in a chain environment.
Upgrade Considerations
This introduces new code for the priceAuthority and fluxAggregator contracts, which will be used to create new instances which will be more performant. The existing vats will be addressed later.
