This fixes blueprint projects not booting on platforms that set LLM_AUTO_ENABLE=1.

This was the sequence of events that led to the problem:
FLowLevelMemTracker::Get().ProcessCommandLine(CmdLine) triggers a call to FGenericPlatformMisc::ProjectDir() too early, before FPaths::IsProjectFilePathSet(). ProjectDir() ends up as ../../../engine/ instead of e.g. ../../../tp_firstperson/. This only happens for blueprint projects because code projects set GInternalProjectName and ProjectDir() follows a different path if FApp::HasProjectName().
In contrast, platforms that set LLM_AUTO_ENABLE=0 early out from the FLowLevelMemTracker function call so they don't trigger the problem.

This leads to ../../../*engine*/Content/Paks/ being created, instead of e.g ../../../*tp_firstperson*/Content/Paks/, making the engine believe there are no paks and fall back to reading from a normal file.
