Logger$PrivateConfig.filter(Level, Marker, String) allocates empty varargs array

While reviewing some JFR profiles, I notice significant allocations of Object[] due to use of some isEnabled conditions that ends up using empty varargs invoking org.apache.logging.log4j.core.Filter#filter(Logger, Level, Marker, String, Object...), for example the following call trace:

at org.apache.logging.log4j.core.Logger$PrivateConfig.filter(Level, Marker, String)
at org.apache.logging.log4j.core.Logger.isEnabled(Level, Marker, String)

We can avoid allocation on this hot path when invoking Filter#filter(Logger, Level, Marker, String, Object...) by reusing an empty object array for the varargs.
