closure capture rule applied at Swift 5.8 doesn't work correctly in resultBuilder

[JCSooHwanCho]

Description
When I tried to compile with Xcode 14.3 RC 2, our company's project codes didn't compile with some reasons. One of that is this case. In resultBuilder closure, using weak capture self with if-let shorthand make capturing semantic error. I made a sample code snippet to reproduce problem.

Steps to reproduce
Try this sample

@resultBuilder
struct VoidBuilder {
    static func buildBlock() -> Void {

    }

    static func buildPartialBlock<T>(first: T) -> Void {

    }

    static func buildPartialBlock<T>(accumulated: Void, next: T) -> Void {

    }
}

final class EscapingWrapper {
    static func wrapper(_ closure: @escaping () -> Void) {
        closure()
    }
}

final class Sample {

    @VoidBuilder
    var void: Void {
        EscapingWrapper.wrapper { [weak self] in
            guard let self else { return } // Implicit use of 'self' in closure; use 'self.' to make capture semantics explicit
        }
    }
}

Expected behavior
compile success without error.
