This commit adds support for a new `kv.watch()` method that allows
watching for changes to a key-value pair. This is useful for cases
where you want to be notified when a key-value pair changes, but
don't want to have to poll for changes.

This commit updates the ext/kv module to use the denokv_* crates for
the protocol and the sqlite backend. This also fixes a couple of bugs in
the sqlite backend, and updates versionstamps to be updated less
linearly.
This patch adds a `remote` backend for `ext/kv`. This supports
connection to Deno Deploy and potentially other services compatible with
the KV Connect protocol.
