FB11244375: Xcode shows an error message when importing a module that declares a typealias to a protocol with a primary associated type

Description

Xcode 14beta5 shows a message stating that "An internal error occurred. Source editor functionality is limited. Attempting to restore..." when importing a module that declare a typealias to a protocol with a primary associated type (and where the alias specifies the primary associated type, generically or not). To reproduce, create a SwiftPM package with two modules A and B having A as a dependency. In the module A, declare:

public protocol Foo<Bar> {
  associatedtype Bar
}
