Update the fee extension 1.0 and add some tests (#2925)

Many of the actual fee extension changes are based off Weimin's PR
https://github.com/google/nomulus/pull/2912, though this makes some
additional changes based on the XML schema and description from RFC 8748.

This adds tests for the DomainCheckFlow which is the most complex and
thorough user of the fee extension, but we'll want to add further tests
to the other domain flows to make sure they're handled correctly.
