Few workarounds for the next manual perf run (#2282)

* define NET7_0_PREVIEW2_OR_GREATER const for .NET 7 Preview2+ builds

* don't use Regex.Count API for older versions of .NET 7 (used as baseline for monthly perf runs)

* don't try to run AddRemoveFromDifferentThreads.ConcurrentStack benchmark on ARM64 as it hangs

details: dotnet/runtime#64980

* don't try to run Json_FromString.Jil_ benchmark on ARM64 as it throws AccessViolationException

details: dotnet/runtime#64657
