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.

- Added memory mapped IO concept to the engine
- Implemented and tested on Windows and IOS
- Not in use by anything yet, however, as the use cases are narrow and special (bulk data that does not need massaging after load - so it can be swapped out and back in silently by OS)

- MeshDescription now held as compressed bulk data and unpacked on demand. This is managed by FMeshDescriptionBulkData.
- Made RawMesh accessors in StaticMesh responsible for performing legacy conversion from MeshDescription if necessary.
- Added FBulkDataReader/FBulkDataWriter for serializing bulk data to/from archives.
- Added FUntypedBulkData::UnloadBulkData() for releasing the bulk data allocation without invalidating it (so it can be reloaded when necessary). Editor only.
- Renamed StaticMesh MeshDescription methods (now GetMeshDescription(), CommitMeshDescription() etc).
- Removed unnecessary mesh description attributes from StaticMesh: those which are used only by Editable Mesh, and transient attributes which are automatically generated when needed for building vertex tangent space.
- Slight change to FAttributesSetBase::RegisterAttribute(): if the attribute specified already exists, it will be amended to adopt the type, passed flags and number of indices. If only the number of indices changes, any existing data will be preserved if possible.
- Added TMeshAttributesRef::Copy() to copy an entire attributes array from one name/index to another.
- Changed implementation of TMeshAttributesRef/TMeshAttributesView to provide a const ref/view if the template type parameter is const. Added TMeshAttributesConstRef/TMeshAttributesConstView as an alias for backwards compatibility.
- Added FMeshDescription::IsEmpty() for determining whether a mesh description has any content or not.
- Removed versioning GUID for mesh description: this should be handled by each mesh description client now.

- Added support for compression plugins
- Removed the Custom compression concept, now using plugins properly
- Modified UnrealPak to use FNames, and allow for multiple compression methods (fallbacks on error or unavailability, etc)
- Added project settings for compression method selection for UnrealPak, and additional settings to be passed to UnrealPak (for instance, to control compression size/speed, etc)
- Deprecated a bunch of old function calls
- Improved pak file "old format" reading ability
- Brought over some changes from Fortnite for pak file encryption and memory savings
- Implemented a parallel compression pull request (#4129) to speed up pak file compression
