Desugaring of try-with-resources.

Adds desugaring of try-with-resources for pre-19 min-sdk
version, it essentially boils down to removing all calls to
Throwable::addSuppressed(...) and replacing all calls to
Throwable::getSuppressed() with empty array of Throwable.

The desugaring requires library and class path since it needs
to inspect/check exception class hierarchy. Disabling it by
default until we measure performance impact.
