Name lookup of typealias in protocol inconsistent for nested types

[benpious]

Description

A typealias is respected for the initializer of a type, but not the type annotation, when it is nested in a protocol.

Reproduction

protocol P {
    
}

extension P {
    
    typealias UUID = Int
    
}

struct S: P {
    
    var uuid: UUID = UUID()
        
}

Expected behavior

This should compile; the meaning of UUID should have changed in both locations.

Environment

Swift 5.9, Xcode 15.3.
