Integrate all cook -iterate optimizations from //UE4/Dev-core/...
Test Scenario:
1) BuildCookStageAndRun with these arguments: -platform=Win64 -configuration=Development
2) CookIterate with these arguments: -run=Cook -CookCultures=en -TargetPlatform=WindowsClient -unversioned -stdout -unattended -iterate
Wall Time Results (as an average of running step 2) two times):
Before: ~09:40 (580 seconds) cook commandlet time
After: ~02:30 (150 seconds) cook commandlet time
=> 07:10 (430 seconds ) faster, i.e. a ~ 3.9x speedup
Win32 FileSystem Results:
Before: 1.5 million GetFileAttribute calls and 1.2 million FindNextFile calls
After: 35 0000 GetFileAttribute calls and 1.6 million FindNextFile calls
=> ~400 000 calls to FindNextFile replaces ~1.5 million calls to GetFileAttribute

If a container element is overridden on an instance, then the entire container is serialized into the instance with different keys than the archetype. This means that all elements of a container need to be gathered if any elements within the container have changed.

This addresses the issue of enormous meshes >2Gb being unimportable (since source model data is stored as bulk data and loaded by the editor on demand).
This *won't* address the related problem that reading a large BulkData into a TArray is still not possible due to the 31-bit index limit on TArray.

The definition of the delegate type must specify the class and property name of the delegate that will use it and the type cannot be used outside of that context or just on the stack.
UMulticastDelegateProperty is now abstract and has 2 subclasses (UMulticastDelegateInlineProperty and UMulticastDelegateSparseProperty). The SparseProperty SignatureFunction will be a USparseDelegateFunction.
The sparse delegates do not work correctly with the python bindings at this point, but this will be visited soon.

- Brings over the necessary engine changes for embedding UE4 mobile as a dylib/so in native mobile app
- Various changes for facial animation, screen recording, others
- ARKit and ARCore plugins were removed, as deemed "not ready"

This fixes crashes where they would take references to things like an actor within a world, and then the active editor world was changed (which verifies against GC reference leaks).
