Wrong emitted metadata for nested generic types

[auduchinok]

The generated types for (at least some) closures miss type parameters from their containing types.
When defining a nested type, it should redefine all type parameters from its containing type (see I.10.7.1 from ECMA-335).

Closures like Internal.Utilities.Collections.AgedLookup`3+-ctor@25-5 miss their parent's type parameters and have only 1 of the 4 type parameters needed. This was caught by an assert in R#/Rider metadata reading code. We're disabling the assert for now, but it looks like the code generation should be fixed on the F# compiler side.

Try with realsig-

@vzarytovskii Can confirm it helps, thanks!

@vzarytovskii Can confirm it helps, thanks!

Thanks. We turned it off by default in rc2, but compiler itself still builds with realsig

Yes this is real ... needs fixing.

[vzarytovskii]

This is fixed in rtm (by rolling back the realsig), @KevinRansom do you want to keep it open to track the fix with realsig+?

[KevinRansom]

@vzarytovskii i do want to keep it open.
