Worker function for DEBUG(). If Error Logging hub is loaded log ASSERT

We use UINT64 buffers due to IPF alignment concerns.
Arguments:
ErrorLevel - If error level is set do the debug print.
Format - String to use for the print, followed by Print arguments.
Marker - VarArgs
BufferSize - Size of Buffer.
Buffer - Caller allocated buffer, contains ReportStatusCode extended data
Returns:
