Treat the `<Module>` type as not having a lazy constructor (#3584)

This was special cased in CorInfoImpl because that's where CoreCLR
special cases it, but the entire system should consider these not having
a lazy cctor. This cctor is triggered differently.

Noticed while working on the IL scanner. Also made this check faster
while I was at it.
