Backport of #76365 to release/7.0
/cc @Maoni0 @PeterSolMS
Customer Impact
Given that we expect some customers will see working set or performance regressions with regions, we want to make sure that clrgc.dll using segments performs just like .NET 6.0 did. So this change disables a gen 1 budget tuning change we did in the 7.0 time frame.
Testing
Ran GCPerfSim scenarios on both WKS and SVR, for both regions and segments.
Risk
Risk should be small because we are undoing a change introduced in 7.0. There is no change for regions, only for segments. Also change is minimal and straightforward.
