Fixes dotnet#105397. The repro case hits an interesting problem in native layout - we emit the `IEnumerable<IEnumerable<double?>>` type as a constructed type, however the components of it are only generated as necessary. Because native layout expresses it as a decomposed instantiation, we're not able to find the type because the component of it is not constructed and we don't really keep track of those. This can be fixed by simply not generating types as composed out of various components if the `MethodTable` already exists in the compilation.
