A PR that addresses part of potential CloudKit rate limiting. We can cache unsynced records in the database and skip a bunch of CloudKit fetching in the process.

Brings in what upstream merged after 1.12.1, unreleased: the upload sort
(pointfreeco#571), quotaExceeded saves parked and sent again (pointfreeco#335, pointfreeco#576), cached
records waiting for their parent (pointfreeco#567), CloudKit rate limiting (pointfreeco#569, pointfreeco#564),
the mock database's modification dates (pointfreeco#574) and the @fetch load race
(pointfreeco#536).

Conflicts, resolved:
- Upload sort: upstream's topologicallyAscending replaces the fork's own
  comparator; the fork's reference violation guard stays.
- enqueueLocallyPendingChanges takes upstream's scope, and still reads,
  queues and removes the queued notes in one write, so a note written while
  sync starts is queued exactly once. Notes written while sync is stopped
  record their database, as upstream's do.
- MockSyncEngineState takes upstream's single State, and keeps the fork's
  hook before adding changes and its rule that only the last save or
  deletion of a record stays queued.
- MockCloudDatabase takes upstream's records(for:) and keeps the fork's
  recordsLookupError and deletionLog.

The fork's own server lookups (settleDependents, the lost deletion and
leftover record checks) go through upstream's batched records(for:), so
they wait and try again when CloudKit limits the request rate.

Tests: MyDelegate is upstream's AccountChangedDelegate now; a share's
snapshot shows cloudkit.title as in upstream's; PreviewTests.delete() waits
for the preview timer's send to return before it ends (the fork's sends do
more after the server changes, and the test ended while one was still
returning in 4 of 5 full runs). Full suite: 421 pass, 6 runs in a row.
