When slicing a blob that is already sliced we should reference it's
parent's data instead of creating a subview into the sliced blob. This
keeps the blob ancestry chain small and reduces the number of blobs that
we have to resolve.

In #36364 I moved both serializable and transferable implementations
from the `script_traits` crate into a single file called
`message_ports.rs`. Gregory raised the point that this was a bit of a
inaccurate grouping. This change attempts to fix it according to the
division in the specification.
