fixes #20454
Current KV queues implementation assumes that `enqueue` and
`listenQueue` are called on the same instance of `Deno.Kv`. It's
possible that the same Deno process opens multiple KV instances pointing
to the same fs path, and in that case `listenQueue` should still get
notified of messages enqueued through a different KV instance.

This fixes the `TypeError: Database closed` error during shutdown.

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.

Properly handle the `SQLITE_BUSY` error code by retrying the
transaction.
Also wraps database initialization logic in a transaction to protect
against incomplete/concurrent initializations.
Fixes https://github.com/denoland/deno/issues/20116.

Extend the unstable `Deno.Kv` API to support queues.

`rusqlite` does not support async operations; with this PR SQLite
operations will run through `spawn_blocking` to ensure that the event
loop does not get blocked.
There is still only a single SQLite connection. So all operations will
do an async wait on the connection. In the future we can add a
connection pool if needed.

This commit updates the `Deno.Kv` API to return the new commited
versionstamp for the mutated data from `db.set` and `ao.commit`. This is
returned in the form of a `Deno.KvCommitResult` object that has a
`versionstamp` property.

This reverts commit 50b793c9ed866ee29e8f04b4fa24b485b01a2b74.

Currently `Deno.openKv(":memory:")` requests read+write permissions for
`./:memory:` even though no file is read or written. Also added some
guards for special sqlite paths that were unintentionally opted into.
|
|
This commit adds unstable "Deno.openKv()" API that allows to open
a key-value database at a specified path.
