Fixes #90333.
We were not generating information about static virtuals on interface types. Information about default interface methods normally goes to the class, but if the T we're dispatching on is an interface, this information wasn't generated. The fix is to put this information into dispatch maps and sealed vtables, same way we do for classes.
The test shows what the problem is - if we change
IBar
to be a class, things would work even before this PR.Cc @dotnet/ilc-contrib
