RFR: 8066869: Add Closeable::closeUnchecked that is the equivalent of close but throws UncheckedIOException

[Remi Forax]

I'm not a big fan of hiding exceptions, why not wrapping the IOException in an UncheckedIOException ?

So closeUnchecked() means close and throw an unchecked exception if an exception occurs.

regards,
Rémi
