Add micro-benchmark validation

[BrennanConroy]

Fixes #27607
Fixes #23025

Open question:
Should projects have to opt-in for validation? If not, we need to align on a folder/project name structure so we don't try to validate non-micro benchmark projects.

This is currently turned off because BenchmarkDotNet hasn't released a package that works with net6.0 yet. Using nightlies I can verify this locally.

On failure:

  Running benchmark validation for:
  Microsoft.AspNetCore.SignalR.Microbenchmarks

  'HubConnectionReceiveBenchmark.ReceiveAsync: Dry(Toolchain=InProcessNoEmitToolchain, IterationCount=1, LaunchCount=1, RunStrategy=ColdStart, UnrollFactor=1, WarmupCount=1) [ArgumentCount=0, MessageCount=1, Protocol=json], 0 runs' failed, reason: 'AllMeasurements'

I'd rather fix the folder structure than make validation opt-in. BenchmarkDotNet hasn't release a package in a while now. Can we use the nightly package feed for our microbenchmarks?

[BrennanConroy]

BenchmarkDotNet hasn't release a package in a while now.

Yeah, I asked and they should be releasing an update in a week or two

[BrennanConroy]

I like the current format for SignalR and Middleware:
C:\aspnetcore\src\SignalR\perf\Microbenchmarks\Microsoft.AspNetCore.SignalR.Microbenchmarks.csproj
C:\aspnetcore\src\Middleware\perf\Microbenchmarks\Microsoft.AspNetCore.WebSockets.Microbenchmarks.csproj

Which would make Kestrel:
C:\aspnetcore\src\Servers\Kestrel\perf\Kestrel.Performance\Microsoft.AspNetCore.Server.Kestrel.Performance.csproj -> C:\aspnetcore\src\Servers\Kestrel\perf\Microbenchmarks\Microsoft.AspNetCore.Server.Kestrel.Microbenchmarks.csproj

Sounds good to me.

@sebastienros We're planning to move and rename the Microsoft.AspNetCore.Server.Kestrel.Performance microbenchmarks. This is just a heads up in case you need to react.

[sebastienros]

I will update our config files when it's merged, and maybe get them running in the perf CI.

Any 's 😃
