Previously, the behaviour of getBestDowngradeVersion was defined in terms of major and minor versions, but this broke as soon as we moved to 9.1.

The proper behaviour is "downgrade back to previousVersion unless that's so old it's incompatible with the current version, in which case downgrade to minimumCompatibilityVersion". I've changed the unit tests to reflect this, and updated the javadocs.

Fixes #124388.
Fixes #121316.
