The tracker base class currently does two things: bump the score in
response to observer notifications, and store a list of changed IDs.
The bookmarks, form autofill, and now bridged trackers need to hack
around this to opt out of persistence, since they handle change
tracking in the storage layer.
This commit keeps the score logic in `Tracker`, but moves all the
persistence code into an intermediate `LegacyTracker` class, and
changes all engines that need persistence to inherit from it.
`ignoreAll` is more interesting. We want new-style stores to emit
observer notifications with change sources, so that the tracker knows
to ignore changes made by Sync. Ignoring all observer notifications
during a sync is a blunter version of this. But, not every new store
supports change sources, so we reimplement `ignoreAll` manually for
ones that don't.

This commit adds syncing support to the `StorageSyncArea` class, via
the Golden Gate library.
It also changes the `BridgedEngine` trait: `initialize` and `finalize`
haven't been useful in practice, since that's managed by the storage
service, and the `LazyStore` takes care of setting up the storage
connection on first use. But, what we do need is a way to signal a
sync is starting, so that the engine can set up temp tables. That's
handled by the new `sync_started`.
Finally, this commit changes `BridgedEngine::set_uploaded` to take a
`sync15_traits::Guid` instead of a `String`.

This commit splits `CryptoWrapper` into a base `RawCryptoWrapper`
class, which only handles encryption and decryption without
parsing the cleartext's contents, and the existing `CryptoWrapper`
class, which works like before.
Our bridged engine subclasses `RawCryptoWrapper`, and
implements some methods to convert records to and from envelopes.
Envelopes are a concept we introduced in `sync15_traits` to pass
along metadata from the BSO wrapper (like the modified time from the
server, and ID, to ensure they match) in addition to the cleartext.
This lets us reuse `sync15_traits::Payload` to parse record payloads
in Rust, and avoids parsing the cleartext in JS, only to stringify it
again when we pass it to the bridged Rust engine.

This commit adds a `mozIInterruptible` implementation to
`StorageSyncArea`, and changes `LazyStore` to get an a-s interrupt
handle and interrupt pending operations.

This commit removes the `nsICancelable` return values from all
`mozIBridgedSyncEngine` methods, and replaces them with a
`mozIInterruptible` interface that can be implemented by store
classes that support interrupting.
The `nsICancelable` pattern was intended to make each operation
interruptible, without affecting the others. But we can't guarantee
that with SQLite, because it only has a way to interrupt all
running statements on a connection, not specific ones. Further,
this pattern doesn't match what we currently do in a-s, where we
create an internal "interrupt scope" for each operation, and hand
out an "interrupt handle" for interrupting all in-progress
operations.
Storage classes like `StorageSyncArea` can opt in to interruption
by implementing `mozIInterruptible`. It's a separate interface to
protect against accidental misuse: because it interrupts all
statements on the connection, it might lose writes if the current
operation is a `set`, for example. But it's useful for testing and
debugging, so we still expose it.
This commit also changes Golden Gate ferries to hold weak references to
the `BridgedEngine`, so that they don't block teardown.

This commit wires up `StorageSyncArea::teardown()` to call the new
`webext_storage::Store::close()` method.
It also changes `teardown` to drop the `LazyStore`, and thus close its
database connection, on the main thread if dispatching to the task
queue fails. Dispatch should only fail at shutdown, and putting the
owned reference back only adds indirection, since the `StorageSyncArea`
will still drop its `LazyStore` later in shutdown.
Finally, it includes an xpcshell test fix for
https://github.com/mozilla/application-services/pull/3050.

Now that `BridgedEngine` has been moved to `sync15_traits`, we can
remove `golden_gate_traits` from the tree, and change Golden Gate to
depend on `sync15_traits` directly.
This commit also adds a Cargo feature, `services_sync`, which reflects
the `MOZ_SERVICES_SYNC` config option. In the future, we'll use this
feature to gate implementations of `mozIBridgedSyncEngine`.

This commit adds a new crate for bridging Rust Sync engines to Desktop,
and a `mozIBridgedSyncEngine` for accessing the bridge via JS.
Naturally, the bridge is called Golden Gate. 😊 For more information
on how to use it, please see `golden_gate/src/lib.rs`.
Other changes include:
* Ensuring the test Sync server uses UTF-8 for requests and responses.
* Renaming `mozISyncedBookmarksMirrorLogger` to `mozIServicesLogger`,
and moving it into the shared Sync interfaces.
The `BridgedEngine` trait lives in its own crate, called
`golden_gate_traits`, to make it easier to eventually move into a-s.
`Interruptee` and `Interrupted` already exist in a-s, and are
duplicated in this crate for now.
