Cache Emulate_IsConfigured result (#7569) 

* Cache Emulate_IsConfigured result

The check is used very often, so this caching reduces necessary
allocations.

* Fix winpr_HexLogDump

Abort function early if the log message is to be discarded due to
the log level being inactive.

* Use common logger for rdpdr message
