fix(ops): disallow memory slices as inputs to async ops (#16738) In Rust, it is UB if a slice is mutated while borrowed except through the slice itself, and it is also UB if a mutable slice is read while borrowed. The op macro allows borrowing an `ArrayBuffer{,View}` as a memory slice for the duration of an op, but this is not sound for async ops, since the `ArrayBuffer` could be accessed from JS during the await points. This PR therefore disallows such automatic borrowing only for async ops. Co-authored-by: Divy Srivastava <dj.srivastava23@gmail.com> 2023-01-15 02:40:01 -05:00			`error: custom attribute panicked`
