Replace `strawberryfields.api.Job` with `xcc.Job`

[thisac]

Context: As part of the XCC integration, there's a new xcc.Job class that will replace the old strawberryfields.api.Job class.

Description of the Change:

• strawberryfields/api/job.py is removed and all uses of strawberryfields.api.Job is replaced with xcc.Job.
• An xcc.Job object is returned when running RemoteEngine.run_async().
• Documentation is updated to explain how to use the returned xcc.Job object when running RemoteEngine.run_async().
• tests/api/test_remote_engine tests are updated and tests/api/test_job.py is removed.

Benefits: The strawberryfields.api.Job class is removed in favour of xcc.Job and we're one step closer to XCC integration.

Possible Drawbacks:

• When running RemoteEngine.run_async() the returned xcc.Job object doesn't return results as a Result object (as before, and as RemoteEngine.run() still does). The user will need to pass the job.result results manually into a Result object.
