Slava Pestov f05d1cab32 Sema: Fix crash when declaring an old-style variadic parameter with nonescaping type ...

This is not supported for the same reason you can't have a noncopyable
variadic parameter, but the code was hard-coded to check for copyability
only.

Generalize this to apply the generic signature for Array via the
common code path, and add a custom note to explain why those requirements
are checked in the first place.

Cleaning this up also fixed some fuzzer crashes.
