Convert sync over async network handling to async

[msft-paddy14]

Currently Garnet's network processing in TLS mode happens by blocking the thread that receives the packet and it waits for TLS processing to complete. This leads to threadpool exhaustion and is an anti-pattern in general. It limits scalability where cores are limited as threads will get blocked and .NET will create more threads (where limit is not set). This makes things worst as memory footprint increases (~8MB per stack) and thread contention increases. We also convert Task to ValueTask for paths where async operation is already completed in general

Looks good. Make sure to run the NetworkBDN and post the result vs main

You can also increment the Version in version.props before merge so that we get a new release with this.

In RawStringOps etc. the BDN calls should be async ... await as you had it earlier. We still need that else the BDN will return before the operation completes.
