[JSC] Add structuredClone to jsc shell and add more tests

rdar://187713459
Reviewed by Tadeu Zagallo, Keith Miller, and Vassili Bykov.
This patch adds structuredClone[1] function to jsc shell. This
implements the spec[2]'s behavior. It allows us to test CloneSerializer
and CloneDeserializer more easily. $262 offers broadcast function which
utilizes them, but still swallows some missing error checks due to its
thread sneding characteristics (in particular, deserializer side because
of capturing it in a different thread). Having structuredClone increases
the test coverage of CloneSerializer and CloneDeserializer.
