process: make tick callback and promise rejection callback more robust

- Rename `internalTickCallback` to `processTicksAndRejections`, make
  sure it does not get called if it's not set in C++.
- Rename `emitPromiseRejectionWarnings` to `processPromiseRejections`
  since it also emit events that are not warnings.
- Sets `SetPromiseRejectCallback` in the `Environment` constructor
  to make sure it only gets called once per-isolate, and make
  sure it does not get called if it's not set in C++.
- Wrap promise rejection callback initialization into
  `listenForRejections()`.
- Add comments.
