* Added support for deserializing BgObject types directly into native classes.
* Removed opcodes for creating graph structures. These are now created in user code from BgObject types.
* Removed BgNodeSpecBuilder. BgNode objects can now be modified directly (returning a modified copy).
* Added concrete types for option parameters. The VM now keeps track of any parameters for evaluated options, allowing them to be added into the graph definition.
* Order dependencies now take nodes rather than outputs.
* Added explicit support for native thunks, whose bindings are saved to a sideband channel during compilation and referenced in bytecode as an index. This generalizes code that was previously specific to node definitions.
* Added a name table to bytecode, to optimize situations where we reference the same string mulitple times.

Ugs - Updated ugs to read the configuration via the shared library, thus removing the support to read it from UnrealGameSync.ini. Added a ini setting to allow which providers to use though, so that we can have more providers listed in the configuration then UGS will want to care about but also to allow us to control opt in of this feature per project.

* ITreeStore defines an API for reading/writing named tree structures.
* ITreeStore<T> allows reading/writing trees of nodes derived from the TreeNode base class, which can be specialized by clients. TreeNode tracks whether the node has been mutated, and allows recursing through the tree with strongly typed objects. Weak references are kept to deserialized TreeNode objects to ensure synchronization with the serialized tree objects.
* Default (and only current) implementation of ITreeStore is BundleStore, which packs nodes together in an efficient binary format and supports incrementally updating bundles. Nodes are hashed and deduplicated within bundles (and the known working set of the BundleStore instance), but packed Bundles are stored using a unique id returned by IBlobStore.
* DirectoryNode and FileNode nodes allow storing file trees in bundles, and implement content-aware chunking of binary data using a rolling BuzHash over an input stream.
