This change consists of multiple changes:
Core:
- Deprecation of ANY_PACKAGE macro. Added ANY_PACKAGE_DEPRECATED macro which can still be used for backwards compatibility purposes (only used in CoreUObject)
- Deprecation of StaticFindObjectFast* functions that take bAnyPackage parameter
- Added UStruct::GetStructPathName function that returns FTopLevelAssetPath representing the path name (package + object FName, super quick compared to UObject::GetPathName) + wrapper UClass::GetClassPathName to make it look better when used with UClasses
- Added (Static)FindFirstObject* functions that find a first object given its Name (no Outer). These functions are used in places I consider valid to do global UObject (UClass) lookups like parsing command line parameters / checking for unique object names
- Added static UClass::TryFindType function which serves a similar purpose as FindFirstObject however it's going to throw a warning (with a callstack / maybe ensure in the future?) if short class name is provided. This function is used in places that used to use short class names but now should have been converted to use path names to catch any potential regressions and or edge cases I missed.
- Added static UClass::TryConvertShortNameToPathName utility function
- Added static UClass::TryFixShortClassNameExportPath utility function
- Object text export paths will now also include class path (Texture2D'/Game/Textures/Grass.Grass' -> /Script/Engine.Texture2D'/Game/Textures/Grass.Grass')
- All places that manually generated object export paths for objects will now use FObjectPropertyBase::GetExportPath
- Added a new startup test that checks for short type names in UClass/FProperty MetaData values
AssetRegistry:
- Deprecated any member variables (FAssetData / FARFilter) or functions that use FNames to represent class names and replaced them with FTopLevelAssetPath
- Added new member variables and new function overloads that use FTopLevelAssetPath to represent class names
- This also applies to a few other modules' APIs to match AssetRegistry changes
Everything else:
- Updated code that used ANY_PACKAGE (depending on the use case) to use FindObject(nullptr, PathToObject), UClass::TryFindType (used when path name is expected, warns if it's a short name) or FindFirstObject (usually for finding types based on user input but there's been a few legitimate use cases not related to user input)
- Updated code that used AssetRegistry API to use FTopLevelAssetPaths and USomeClass::StaticClass()->GetClassPathName() instead of GetFName()
- Updated meta data and hardcoded FindObject(ANY_PACKAGE, "EEnumNameOrClassName") calls to use path names

Additionally auto-import any namespace associated with the selected component class type when a new component is added.
Change summary:
- Modified the component type registry to internally create/store unloaded BP data to assist with unloaded BP component type filtering.
- Added FEditorClassUtils::GetImplementedInterfaceClassPathsFromAsset() to move BP interface asset tag processing into a shared utility API.
- Modified SComponentClassCombo to work with IClassViewFilter-style filtering and added a filter options menu (currently only visible when namespace filtering features are enabled via CVar).
- A few minor modifications/additions to SSubobjectEditor/SSubobjectBlueprintEditor to assist with interfacing with the owning FBlueprintEditor context for filtering, updating etc.

FClassHierarchy::PopulateClassHierarcy: Refactor for robustness.
Instead of creating a tree for classes-from-blueprint and a tree for classes-from-loaded-UClass, create a single map from ClassPathName to node, and populate the data-from-blueprint and data-from-loaded-Uclass on the same node, and then create a tree from that map.

Additional changes:
- Deprecates the previous method for specifying a singular custom class viewer filter and updates all existing occurrences of this pattern in engine code.
- Extends the property editor utilities interface to expose custom class filter(s) that can be applied to the class picker widget used for editing class property values.
- Adds an implementation of this interface to SDetailsView such that additional class filter(s) can now be configured to be applied to all underlying class property nodes.

LIMITATIONS:
1) Re-instancing will only update UClass instance data.
2) Adding and removing properties should only be done towards the end of a class or structure and can not be followed by complex data types.
3) Adding and removing properties from a base class should not be done if a derived class contains complex data types.
KNOWN ISSUES:
1) Changes to enumerations and structures will not be reflected in existing blueprints. However, adding new nodes to the blueprint will show the updated enumeration or structure.
2) If a class contains an enumeration or structure as a member, the class will not be re-instanced if enumeration or structure is changed.
CHANGES:
1) LiveCodingServer
1a) Modified to always execute certain static instances during load.
1b) Modified to exclude the _Statics static structures to avoid patching to old copies.
2) Added support for LiveCoding reinstancing
2a) Refactored deferred registration system for UClass, UEnum, and UScriptStruct to use a common system that works for normal game, hot reload and live coding.
2b) Type specific version check data is possible (i.e. enum doesn't have a size)
2c) Single registration static for UClass
2d) Single registration class for all types that is just a blind forward to API.
2e) Static and dynamic registrations use different API entry points to avoid having overloaded argument lists that just apply to one or the other.
2f) Shims for older API
3) New common "Reload" system to avoid using HotReload code.
3a) Support common delegates regardless of who is reloading/reinstancing.
3b) Re-instancing code moved from HotReload to Kismet2 (where the bulk of the re-instance code already existed).
3c) Modified PyWrapper to use new helper class instead of depending on HotRelaod
3d) Added WITH_RELOAD which is defined if HotReload or LiveCoding is enabled.
3e) Modifed existing code to use new #define and delegates.
Robert did the review on the changes covered by Part 2. Remaining changes are all straightforward.
