Motivated by aspnet/Benchmarks#1908 where we were making startup time with DATAS even worse during the .NET 8 endgame, but this has been a problem from the beginning.

Comparing with workstation GC, server GC with DATAS seems to be making startup time about 2x worse for Native AOT in the Stage1 benchmark. It would be good to do something about it. This GC configuration (that we made the default for ASP.NET in 8.0) appears to be making startup a lot worse than it could be. 2x worse feels excessive.
