- Any code causing a linker mismatch needs to explicitly clear loading flags for their object to avoid asserting. This is to make the intention clear that rename will make loading correctly impossible when moving the object to a different linker unintentionally. So either clear the loading flags of the object (i.e. finish loading via load calls such as ConditionalPostLoad) or forcibly allow mismatching via the new flag.
- When marking an export as invalid in FLinkerLoad::InvalidateExport() we now also clear loading flags since it is wasteful to load invalid objects.
- Exports marked as invalid are no longer reset to be valid when the linker is reset for the object instance. This is to prevent reloading invalid objects when re-using a linker already resident in memory if a subsequent package load is requested.
- When UStruct upgrades UFields to FFields, the UStruct objects are marked as invalid to prevent reloading the objects unnecessarily
- Fixes an issue where since Rename can clear the linker for mismatched types, any calls to FLinkerLoad::InvalidateExport needs to be moved before the rename operation to be effective.
- CollectUnreachableObjects will no longer mark unreachable objects as invalid in the linkerloader. That code would mark objects as invalid until the linker is destroyed which incorrectly assumed would happen soon. If however a load for the same package occurs before the linker is destroyed, the in-memory linker would be re-used keeping the marked exports as invalid so those exports would not be loaded (even though they should have been).

[RN] UObject::Rename will always remove the renamed object's linker if the rename moves the object into a different package. As a result, any renames occuring while an object is loading will now assert instead of leading to hard to diagnose crashes long after the Rename call has completed. If renaming to a different package is intentional and the linker should not be cleared, the new flag REN_AllowPackageLinkerMismatch can be used to prevent clearing linkers on the object even though the linker is for a different package than the package has been renamed to be part of.

IDragDropExtension:
- Extension class providing CanDropOnTarget and GetDropFailureText functions.
FDragDropExtensibilityManager:
- Maintains a list of IDragDropExtensions.
IHasDragDropExtensibility:
- Extension class providing GetDragDropExtensibilityManager function.
IUMGEditorModule:
- Inherits IHasDragDropExtensibility.
FUMGEditorModule:
- Creates FDragDropExtensibilityManager instance on startup.
FDragDropExtension:
- MVVM IDragDropExtension implementation. CanDropOnTarget returns false if the target widget has a UMVVMBlueprintViewExtension_PanelWidget extension.
FModelViewViewModelEditorModule:
- Adds FDragDropExtension on startup and removes on shutdown.
FWidgetBlueprintEditorUtils:
- Added CanDropOnTargetExtensions function which iterates current IDragDropExtensions (via UMG module's FDragDropExtensibilityManager).
ProcessHierarchyDragDrop:
- Checks FWidgetBlueprintEditorUtils::CanDropOnTargetExtensions.

UMVVMBlueprintViewExtension:
- Added virtual OnPreviewContentChanged function.
UMVVMWidgetBlueprintExtension_View:
- Added GetAllBlueprintExtensions function.
FBlueprintViewDesignerExtension:
- New designer extension which overrides PreviewContentChanged and calls OnPreviewContentChanged on each UMVVMBlueprintViewExtension.
FBlueprintViewDesignerExtensionFactory:
- New designer extension factory which creates a FBlueprintViewDesignerExtension.
UMVVMBlueprintViewExtension_PanelWidget:
- Added NumDesignerPreviewEntries property.
- Added static CreateDesignerPreviewEntries function which clears panels children then adds specified number of entries.
- Overrides OnPreviewContentChanged which calls CreateDesignerPreviewEntries using the preview panel widget.
FModelViewViewModelEditorModule:
- Adds PanelWidgetExtensionFactory on module startup and removes on shutdown.
FMVVMPanelWidgetExtensionCustomizationExtender:
- Added "Num Designer Preview Entries" property row.
- Calls UMVVMBlueprintViewExtension_PanelWidget::CreateDesignerPreviewEntries when entry class, slot template or "Num Designer Preview Entries" properties change.

IClipboardExtension:
- Added virtual CanWidgetAcceptPaste function.
FClipboardExtension:
- Overrides CanWidgetAcceptPaste. Checks if specified widget has any UMVVMBlueprintViewExtensions.
FWidgetBlueprintEditorUtils:
- Added static CanPasteWidgetsExtension function. Checks CanWidgetAcceptPaste on all IClipboardExtensions.
FWidgetBlueprintEditor:
- CanPasteWidgets now also calls FWidgetBlueprintEditorUtils::CanPasteWidgetsExtension.
