kevin macaulayvacher 2576f229f2 Changes FAssetHeaderPatcherInner to leverage the CoreRedirect system for resolving FNames in a package header, and string paths when context about the string itself is well known (i.e. we know the string data is a stringified ObjectPath/PackagePath, or ObjectName are deducible). We still make use of string scanning replacement mechanism but those are now constrained to only patching strings content specifically (e.g. Tag data) ...

- Added FAssetHeaderPatcher::FContext for storing data on how to perform a patch (which redirects to follow, string -> string replacement map). Allows for an extensibility point for encapsulating special case patching so we don't need to  rely on string->string mappings exclusively
- Added `virtual FArchive& operator<<(FTopLevelAssetPath& Value)` to `FActorDescArchive` to allow for patching of FTopLevelAssetPath directly. Without this overload the FNames within a FTopLevelAssetPath would be patched one at a time losing all context about what the FNames are.
- Removed IAssetTools::GetAdditionalPatchCopyMappings, GetPatchCopyMappingsForRootRename, and PatchCopyPackageFile as these methods were internal and using the patcher directly should be preferred.
- Added some unit tests for the FAssetHeaderPatcherInner implementation works to codify the assumptions and expectations of the patcher implementation

Set use HeaderPatching as true by default for CopyProjectWithHeaderPatching. AdvancedCopy still disables header patching (to be enabled in a follow-up change)
