Adapt Tarjan generic cycle detector for use in Crossgen2 (#71426)

This change modifies Crossgen2 to use the generic cycle detector
originally implemented for NativeAOT to trim infinite generic
expansion as observed in the LanguageExt public nuget package
and tracked by the issue

https://github.com/dotnet/runtime/issues/66079

For now the generic cycle detector is opt-in as it's relatively costly
in terms of compiler performance and it seems to be a relatively
niche case. We can follow up by optimizing the detector if it turns
out to be more prevalent or if we make the call to turn it on by
default, I have mentioned several options for that in the PR.

Thanks

Tomas
