pj kack 8bbfe7b7af Optimize UPackage::IsFullyLoaded() for cooker. ...

The editor specific feature of querying the file system to identify newly created packages (not having a corresponding file on disk) is really slow.
Early out from this expensive check when the package already has a known file size.

VTune user-mode cpu sampling time results when cooking a big data set (~200 000 packages):
UCookOnTheFlyServer::MaybeMarkPackageAsAlreadyLoaded() down from 10 sec to 0.1 sec, a 100X speedup.
FLinkerLoad::LoadAllObjects down from 400 sec to 280 sec, a 1.4X speedup, i.e. ~4% (120 sec) of the total load time of 2750 sec.
