Also added a default input unit that is used when no units are specified on a text input.
This addresses UE-11863 and UE-9313

- 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.

Core - Added AtomicallySetFlags/ClearFlags to UObject, added a comment to ThisThreadAtomicallyClearedRFUnreachable
[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)
[CL 2498053 by Dan Oconnor in Main branch]
These can be generally described as removing redundant condition checks, using logical operators instead of bitwise operators, removal of redundant parenthesis, and consistent use of pragma push and pragma pop. There is very little observable behavior change in this CL.
Changes that required further review are pending in 2489753

UE-9554 - Add BP/C++ Component's Show all classes list not expanded by default
It now hides the Object root if UObject is not a valid base class type, as this allows the next level of classes to be expanded out which looks much better when adding new component classes.
This involved a lot of shuffling of module dependencies so that we could link GameProjectGeneration to ClassViewer, as previously ClassViewer was directly linking to GameProjectGeneration.
I went through and fixed everything that was linking to GameProjectGeneration to instead list it as a dynamic dependency (which it is, as nothing needs to link to it), and then verified that everything was using ClassViewer correctly (found some places that were only marking it as a dynamic dependency without also adding it as an include module, causing issues with missing API macro definitions as they were including ClassViewer headers via a relative include path).

UE-9699 - Fixing all the places we were setting the asset size to 0 explictly, the new default reasonable size is .1, all asset pickers now just use the default, unless they're the content browser.

- Removed colored text from fields in the SCS editor and replaced with "(inherited)"

[CL 2448738 by Matthew Griffin in Main branch]
Editor - The asset pickers now all save their changes to size so that you don't have to resize it every time you go to pick an asset.

#jira UE-7808 - Editor slows exponentially when selecting an instanced static mesh in viewport that has a large number of instances
[CL 2427864 by Richard TalbotWatkin in Main branch]
[UE-8147] - Details window locks as before, updated work with the component tree
- Once locked, can change component selection to update the details, but the level selection is not affected
- After unlocking, any component selection will force the level selection to match
