Deal with split between IFoo and IHwFoo.

Add two macros that allow us to:
- Retrieve an interface instance with
  a specific name and version. The implementation
  of this will try to retrieve the interface from
  the hwservicemanager. If that fails, in the future
  it can try to retrieve a pass-through version.
- Register an interface implementation. The implementation
  of this automatically wraps it in a hwbinder object if
  necessary.

Also changed IServiceManager to work correctly with the new
macros in libhwbinder.

TODO (b/30584126): the versions should not need to be passed in,
but instead be retrieved from the generated interfaces directly.
