[18.0][REF] queue_job: remove deprecated and not used methods

[florentx]

These parts were marked as deprecated since Odoo 12.0.

Also the comparison methods on Job are misleading:

• the sorting_key returns a tuple containing a missing attribute seq --> AttributeError
• so it means that this comparison never worked
• and obviously, it is not used anywhere, it is just confusing
• meaningful ordering happens on odoo.addons.queue_job.jobrunner.channels.ChannelJob

Hi @guewen,
some modules you are maintaining are being modified, check this out!

Thanks

Code reviewed (improved code coverage on negative lines of code 😁), functionally tested (ran several hundred varied data import queue jobs) and organically tested (fooled around with sorting in user interface).
