If you import a mesh that adds bones to a skeleton, but don't save the skeleton, it could cause a crash.
Added the ability to recover these bones in the editor.

The majority of asset reimport machinery is now held within UAssetImportData and FAssetImportInfo. This change allows us to remove the CachedAssetsBySourceFileName map from FAssetRegistry that was previously added to support auto reimport for 4.7.
The functionality of CachedAssetsBySourceFileName has been wrapped up in FAssetSourceFilenameCache, which sits on top of the asset registry in the editor.
This unification allows us to also consistently store the file timestamps and MD5 hashes of imported files. This subsequently allows auto-reimports to be ignored where a source content file has not actually changed (its MD5 is the same).
This addresses UETOOL-365 - Rework AssetRegistry changes to support auto-reimport

#jira UE-15787 - Creating a child blueprint of an anim blueprint does not result in an anim blueprint
#reviewedby Benn.Gallagher

- An existing local foliage type assigned to the same mesh is no longer stomped by proc foliage from a blueprint class
- Added limited support for foliage type blueprints to the foliage palette
- Properties cannot be edited in the palette, but any changes to the BP propagate to the corresponding instances in the world. In general, using FoliageType assets for proc foliage is still recommended.
- No longer possible to assign the same mesh to multiple local foliage types
- Added source asset info to foliage palette item tooltips
- Local foliage types are now transactional
- Updated asset color for proc foliage spawner and foliage type
[CL 2539880 by Dan Hertzka in Main branch]
Paper2D: Defined a "Paper2D" category and moved existing asset type actions over
New methods on IAssetTools:
- RegisterAdvancedAssetCategory
- FindAdvancedAssetCategory
- GetAllAdvancedAssetCategories
Upgrade Note: This gets rid of the named extension sections in the filter menu, which should instead be extended via registering a new category.

- Linkers are no longer UObjects. Renamed ULinker, ULinkerLoad and ULinkerSave to FLinker, FLinkerLoad, FLinkerSave respectively
- Linkers are now associated with their UPackages
- Linker version is now stored in UPackages
- Async loading is now performed on a separate thread (if platform supports it and only in cooked builds), with the exception of PostLoad which is still done on the game thread
- Added UObject::IsPostLoadThreadSafe() function to determine if PostLoad is thread safe and can be executed on the async loading thread (defaults to false)
- UObject creation is now thread safe and can be performed on any thread
- Move many of the linker/UObject globals into FUObjectThreadContext (TLS)
- GetAsyncLoadPercentage() now takes PostLoad into account
- More async loading stats
- Added AtomicallySetFlags/ClearFlags to UObject
- Made FModuleManager thread safe.
- Added FGCScopeGuard as means of preventing GC from executing from non-game thread
- It's possible to disable async loading thread through ini settings.
- Cancelling async loading will now also trigger GC
- Implemented a basic version of async streaming priorities.

[CL 2498249 by Robert Manuszewski in Main branch]
I have reviewed each change carefully, but it is a large change and I could have missed something! Here is a summary of the types of changes in this CL:
* Made nullptr checks consistent (the plurality of the changes are of this type)
* Completed switch statements (IE, switch did not explicitly handle default case, but had unhandled enum entries - this is the second most popular type of fix)
* Removed unused variables
* Removed redundant initializations
* WidgetNavigationCustomization.cpp was fixed by the owner
* integers converted to floats where result was stored in a float
* Removed redundent null checks (e.g. before delete statements)
* Renamed variables to prevent non-obvious shadowing
* Fixed use of bitwise & when checking for equality to an enum entry (which is often 0)
* Fixes for some copy paste errors (e.g. FoliageEdMode.cpp)
