@preconcurrency on a function typealias has no effect

[dnadoba]

Describe the bug
@preconcurrency on a function typealias has no effect. It should either have an effect as to would on a method taking a function or produce a diagnostics that it is not supported.

Steps To Reproduce

@preconcurrency typealias Callback = @Sendable () -> ()
func methodWithPreconcurrencyOnTypealias(callback: Callback) {}
@preconcurrency func methodWithPreconcurrencyOnMethod(callback: @Sendable () -> ()) {}

func usage() {
    var mutableVariable = 0
    methodWithPreconcurrencyOnTypealias {
        mutableVariable += 1 // sendable warning
    }
    
    methodWithPreconcurrencyOnMethod {
        mutableVariable += 1 // no sendable warning
    }
}

Expected behavior
It would be best if we wouldn't get a warning and methodWithPreconcurrencyOnTypealias(callback:) would be treated the same as methodWithPreconcurrencyOnMethod(callback:).
However, typealias is no listed in SE-0337 as a a nominal declaration where the @preconcurrency attribute can be used and therefore should at least produce some diagnostics.
