Michael Gottesman d0938a906f [move-only] Ban resilient noncopyable types. ...

One can still in resilient frameworks have noncopyable frozen types.

This means that one cannot make a noncopyable:

1. Full resilient public type.
2. @usableFromInline type.

NOTE: One can still use a frozen noncopyable type as a usableFromInline class
field. I validated in the attached tests that we get the correct code
generation.

I also eliminated a small bug in TypeCheckDeclPrimary where we weren't using a
requestified attr check and instead were checking directly.
