Improved sync speed by resolving the N+1 query issues.
Solves #1402 and Solves #1453
With this change there is just one query done to retreive all the
important data, and matching is done in-code/memory.
With a very large database the sync time went down about 3 times.
Also updated misc crates and Github Actions versions.
This is a rather large PR which updates the async branch to have all the
database methods as an async fn.
Some iter/map logic needed to be changed to a stream::iter().then(), but
besides that most changes were just adding async/await where needed.
Note: The original Vaultwarden implementation of Bitwarden Send would always
hide the email address, while the upstream implementation would always show it.
