Refactoring option parser for UL

As we discussed in PR for JDK-8271186 and in its CSR, we want to introduce `foldmultilines` to stdout/err UL output. However we have no chance to configure `LogOutput` for stdout/err (`LogStdoutOutput`/`LogStderrOutput`) becasuse they will be instantiated statically in logFileStreamOutput.cpp.

So we need to refactor UL option parser to propagate options to all extended classes of `LogOutput`.
