[LOG4J2-668] AsyncAppender ignores RingBufferLogEvents from AsyncLoggers (when all loggers async by setting context selector)

Description

AsyncAppender's #append method currently has this code:

if (!(logEvent instanceof Log4jLogEvent)) {
    return; // only know how to Serialize Log4jLogEvents
}

When all loggers are made asynchronous by setting Log4jContextSelector to org.apache.logging.log4j.core.async.AsyncLoggerContextSelector, they produce RingBufferLogEvent instances, not Log4jLogEvent. These log events will be dropped by AsyncAppender.
