[CL 18823575 by robert manuszewski in ue5-main branch]
Blueprint real number support.
This change deprecates the use the of "float" and "double" types in Blueprints in favor of a new "real". By default, "real" is back by a double precision floating point number. However, it can be single precision if the number is a native float property or function parameter. This distinction won't be visible to the Blueprint user: in both instances, they'll be represented by "real" pin types. During deserialization, we'll automatically convert Blueprint pin types to use real/doubles, unless they're used to represent native code (including delegate signatures).
One consequence of this change is that we need to perform implicit casts between single and double precision real numbers. During Blueprint compilation, the compiler will detect points in the graph for when either a widening or narrowing conversion needs to occur. Subsequently, the script bytecode will contain a new cast instruction that performs the conversion. This also works on container types, but each entry in the container will have to be converted. This can introduce unwanted overhead for large containers that are frequently passed between Blueprint and native code.
The scope of this change affects Blueprints used by Gameplay, Animation, Control Rig, and UMG.

- 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 will allow us to store per payload info in the future such as disabling virtualization for specific payloads.
- Currently there are no flags.
- Older trailer formats will update automatically.

-----------------------------------------------------------------
Fix asserts/warnings around child anim BPs
Ensures that cleaned-up sparse class data structs are moved out of the package they are in, thus not requiring a GC step to ensure that batch compilation works correctly.
Without this, it is possible for the NewObject call in FAnimBlueprintCompilerContext::RecreateSparseClassData to attempt to re-use (as it has a fixed name) the currently-existing (but not referenced) object rather than creating a new one.
This also reverts some other changes that were made to try to address related issues.

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.

- 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.*"
