Swift: Initial creation of the Swift-Go Bridge

Currently working (albeit without unit tests):
  - Getting the framework to dynamically link to the generated CGo lib for the simulator
  - Initializing the library and passing (limited) logging options (but nothing going to Swift)
  - Creating handles for back and forth to Go-owned objects, memory management without passing pointers
  - Creating contexts, async cancelling them, and setting deadlines
  - Async low-level RPC, but without any arguments or VOM-decoding/encoding
  - Generating VErrors to pass to Swift either via a futures callback or as a passed pointer
