@Sendable should not be allowed to precede @escaping

[mattmassicotte]

Motivation

Today, this code compiles.

func myFunction(_ closure: @Sendable @escaping () -> Void) {
}

Proposed solution

@sendable is part of the type. I think this is just a parsing quirk.

Alternatives considered

I suppose would could just leave this as-is. But it allows for some pretty muddy and confusing syntax. Fixing this is a breaking change, but I still think it should be addressed.
