simpleperf: avoid getting event name in EventFd::OpenEventFd. GetEventNameByAttr() uses linear search and is slow. Using it in EventFd::OpenEventFd() has visible effects in cmds like `stat --per-thread -a`. So don't use it in EventFd::OpenEventFd(). Instead, pass event_name as a parameter. Bug: 146220391 Test: run simpleperf_unit_test. Change-Id: Ie7fde5add3c8f20d110916cc280a9c5d4077417f
