Ross Light 3c0eaf830e goose: refactor *gen.inject ...

The function had grown too long. Several related cleanups:

- Factored out the function return value logic, which had been
  duplicated between providers and injectors.
- Moved code generation for different provider call types into separate
  functions. This moves injector-specific state to a new type
  injectorGen to keep the parameter count down.
- Since it's infeasible to keep the "shadow pass" collecting import
  identifiers in sync the spread out logic, the injector code
  generation is just run twice, with initial output discarded.
- Removed the zero value logic left over from Optional.
