[Microbenchmarks] TFMs cleanup + Microsoft.Extensions* update

[adamsitnik]

I've investigated dotnet/runtime#77900 (comment) and the reason behind the "regression" was not using the appropriate version of Microsoft.Extensions*. These particular libraries and not shipped as part of .NET SDK (they are often called OOB: "out-of-band") and they require manual version update in the .csproj. Since 7.0 versions of all Microsoft.Extensions* packages were shipped to nuget.org yesterday, it was a perfect moment to update them and the System* libraries.

But the System* libraries don't support net461 anymore:

System.Security.Cryptography.Pkcs 7.0.0 doesn't support net461 and has not been
tested with it. Consider upgrading your TargetFramework to net462 or later. 

So I've upgraded net461 to net462.

Then the other warning I was getting was:

The target framework 'net5.0' is out of support and will not receive security updates in the future.

So I've removed the net5.0 tfm. And last but not least, I've limited the test projects to target single tfm (net7.0)

fixes dotnet/runtime#77900
fixes #2079
