rev 59757 : Add whitebox support for deflating idle monitors including ObjectSynchronizer::request_deflate_idle_monitors(); drop ObjectSynchronizer::_is_special_deflation_requested flag, functions and uses; switch to ObjectSynchronizer::request_deflate_idle_monitors() as needed; _last_async_deflation_time_ns should be set at the end of async deflation;
