Expose SetSDKForStruct and SetResourceForStruct in templates (#140)

Description of changes:
Makes `setSDKForStruct` and `setResourceForStruct` public, so that they are accessible for other parts of the generator. Exposes `SetSDKForStruct` as `GoCodeSetSDKForStruct` and `SetResourceForStruct` as `GoCodeSetResourceForStruct` in the generator, and includes `SDKAPI` as a template variable to allow querying of API shapes to use with parameters in the new template methods.
