Only return true from FIoDispatcher::IsInitialized() when the script objects chunk exists to keep its behavior consistent. Later, this function will be deprecated in favor of a function on IAsyncPackageLoader.

This is a defensive change to more uniformly gate conditions of various pathways that want to "nice" CPU consumption when the application is not the foreground application (doesn't "Have Focus"). In benchmarking scenarios we don't want a focus-grabbing application to cause change in behavior while taking performance measurements. This could be in local workstation benchmarking where other foreground apps will naturally come to the front or in data center build where antics that might otherwise be completely unknowable could impact benchmark measurements.
This change was formulated after finding some "nice" CPU conditionals that were instrumented, but not all of them are. This change aims to prevent having to instrument, profile, and mitigate each condition separately.

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.

The messaging system destroys these objects with FMemory::Free, which has different alignment logic than operator new when ASAN is used, resulting in a crash.

The new API uses exported functions and cannot be included with the old API without compile errors in existing code that has an include-only dependency on DDC.

All games now use Engine Oodle for runtime decompression
Oodle in Engine can load an older Oodle DLL for encoding packages to keep making the same binary data

Updating FVirtualizedUntypedBulkData and textures to use the BulkDataRegistry.
BulkDataRegistry: Add get/put accessors for the cached BulkDataList of packages.
EditorDomain: Move ClassDigests into a global variable that can be shared with BulkDataRegistry.
EditorDomain: Improve performance of GetFileSize by fetching metadata only.
Tickable Cook Objects, for systems used by the cooker that need to be ticked.
Implementation of the the BulkDataRegistry that uses the DDC cache for persistent storage of the BulkDataList.
