When reloading an existing UPackage make sure to always set all serialized package flags again since they may have been cleared since the last load.
One example is UWorld::FinishDestroy that may clear PKG_ContainsMap on its world UPackage.

- Remove slowtask throttling during load as it could prevent meaningful top level slowtask to be created
- Fix delayed slowtask that was never showing when children were added before the delay
- Add missing slowtask handling on long gamethread functions to improve UI responsiveness
- Add PIE preparation slowtask scopes
- Test to make sure the total amount of time spent in all slowtask functions is reasonable (1s on a 2 minute map load)

BulkDataRegistry: Wait until the top-level EndLoadPackage, and wait until after OnEnginePostInit, before deleting bulkdatasize records. Deleting them sooner can make them be deleted before they're used by the EditorDomain if the EditorDomain's TrySavePackage triggers package loading and a recursive OnEndLoadPackage.

- Text format now includes import and export tables instead of discovering import while serializating exports. This is required to have enough information about objects with an override package that have their Outer in another package.
- UObject Json formatters now export import/export indices instead of relying on the objects full paths, which index into the exported import/export tables.
- Merged code to serialize UObject* and FObjectPtr in Json formatters to avoid code duplication.

- A lot of files have been touched but most of this is changing FPayload::IsValid to !FIoHash::IsZero, the main changes are in EditorBulkData/EditorBulkDataTests
- The only difference between FPayloadId and FIoHash is that the former considered the hash of an invalid or empty buffer to be 'invalid' too where as FIoHash would return a valid hash
-- To keep behaviour the same, we only hash payloads in EditorBulkData using a utility method ::HashBuffer which will not hash empty or invalid payloads and return a default FIoHash instead.
-- Unit tests have been extended to prove that the behaviour has not changed.

This should saves around ~1.5 Mb to ~3 Mb at runtime with ~50000 packages
Added a new core define UE_STRIP_DEPRECATED_PROPERTIES that could be used to wrap deprecated properties and strip them to regain memory when a projects becomes compliant. this can be set in the project target file
Deprecated most public properties from UPackage and created accessors for them

- A cvar named "Serialization.RehydrateOnSave" now controls if we rehydrate a package on save, defaulting to false.
-- At the very least we will need to be able to turn this to true to run any "rehydrate the project" UAT command in the future.
- The package trailer no longer stores a valid compressed size for a payload. In the best case scenario we only know the compressed size of the payload when it was still stored on locally on disk. Each virtualization backend is free to take the payload and recompress it anyway it sees fit etc.
- When duplicate payloads entries are added to a FPackageTrailerBuilder we now keep the original payload entry and discard the duplicate rather than replacing the existing entry with the duplicate, which was the original intent.

- EditorBulkData payloads that are updated in PostLoad were being added to the package trailer builder for local access when saving the package for the editor domain.
- The package trailer system is not able to support this (although this will change soon) so when this occurs we should force those payloads to the legacy serialization path.
- Cleaned up ::ShouldUseLegacySerialization by factoring out the code that is actually affected by UE_ENABLE_VIRTUALIZATION_TOGGLE is wrapped in it, making things easier to read.

- The goal is to show a clear separation between the bulkdata object and the virtualization system.
- NOTE that all of these classes were added during 5.0 development so we are just renaming and moving them, no deprecation paths.
- Renamed FVirtualizedUntypedBulkData to FEditorBulkData
-- Also removed the derived templated types, they were never actually used
- Renamed FVirtualizedBulkDataReader to FEditorBulkDataReader
- Renamed FVirtualizedBulkDataWriter to FEditorBulkDataWriter
- Moved the renamed classes to the UE::Serialization namespace from UE::Virtualization
- Renamed the files of the renamed classes where required.
- Replaced use of LogVirtualization with LogSerialization.
- Renamed defines prefixed with VBD_* to UE_ and make sure they are undefed by the end of the cpp
- Edited unit tests to show up under "System.CoreUObject.Serialization.EditorBulkData.*"
