pw_rpc: Support testing services with mixed protobuf libraries

- Replace the public internal method lookup generated functions with a
  private array of method IDs. Create a MethodLookup class that is
  friended by generated services to access this array.
- Use the generated method ID array to support method lookup in services
  with multiple different protobuf implementations (Nanopb and raw).
- Ensure that the correct method implementation is selected when looking
  up a method at compile time. This prevents accidentally accessing a
  Nanopb method as a raw method or vice versa in a test method context.
