Networking

• Small performance improvements for message deserialization at the networking layer.

Move

VM

• Updated type size calculation to account for all nodes in non-substituted types. Also introduced TypeBuilder struct to construct types with maximum depth and count.
• Added a procedural macro bytecode_spec so that inline specifications to the Move bytecode instructions can be defined in Rust.
• Added runtime environment outside of VM. The env can be used cached and possibly shared across VM instances.
