This is more consistent with the DOM API, and is clearer w.r.t. which values
are available in the lexical environment of the Worker.

Shell::SerializeValue was using a HandleScope, but was also storing Handles in
an ObjectList. The ObjectList handles would persist after the function had
returned, but will have already been destroyed by the HandleScope, so there is
a use-after-free.
This change removes the HandleScope in Shell::SerializeValue and relies on the
caller's HandleScope.
