W^X on Mac for EF Core tests is very slow

[cincuranet]

EF Core was running on Mac with W^X disabled (COMPlus_EnableWriteXorExecute=0) because of #70758. Removing the COMPlus_EnableWriteXorExecute now makes the test run extremely long - usually tests on Helix (where this was applied) run in under 60 minutes. With COMPlus_EnableWriteXorExecute=0 removed these did not finish within the timeout of 3 hours (detail).

The PR that removes the W^X workaround: dotnet/efcore#36243.

It's AMD64 (on OSX.13.Amd64.Open Helix queue).

@cincuranet, is this a blocking issue for 10? Assume you dont see the same issue on arm64?

@mangod9 It is not a blocking issue for 10. I don't know about ARM64, I'd have to manually queue a build into internal Helix queue. Do you want me to do it?
