[builtins] Use length field in TypedArrayConstructByArrayLike.

The byte_length field of the TypedArray is not set to 0 on neutering,
but JSArrayBufferView::byte_length() returns 0 if WasNeutered() is
true. We should use the length property here instead.

We can just short-circuit if the length is 0. Added checks to the
memcpy path that assert length and neutered status are sane.
