This removes all usages of GetBackingStore in crypto. See the
linked issue for an explanation.

Note: I am not sure of the lifetime semantics intended by
ArrayBufferOrViewContents -- I am pretty sure it is correct based on a
manual audit of the callsites & by analogy to ArrayBufferViewContents,
but please ensure that it is correct. If we are at all unsure of the
safety here, I would prefer to abandon this change.

It is error-prone to copy or heap-allocate `ArrayBufferViewContents`,
because you might accidentally cause it to exceed the lifetime of its
argument. Let's make it impossible to do so. Fortunately we were not
doing so anywhere already, so this diff is purely defensive.

I understand why this exists, but it feels somewhat strange to explicitly allow passing in empty Locals.

I agree. An alternative would be to allocate an empty ArrayBuffer and pass it into this function. None of the current callsites looked particularly hot, but I wasn't sure.

Do you think that would be acceptable wrt to performance?

(P.S. if your concern here is blocking, feel free to request changes on the PR.)
