Shouldn't a user get some kind of feedback if they called this on something which they expected to have a poll implementation?

Feedback of what sort? Whether or not one has to run this function is very much backend dependent so I don't want like an exception being thrown if a user calls it on a backend which doesn't need it.
Add a poll method to ports, a master poll method to the Accelerator, and the ability to poll from the service thread. Also, only spin up the service thread if it's requested. The service thread polling (in particular) required some ownership changes: Accelerator objects now belong to the AcceleratorConnection so that the ports aren't destructed before the service thread gets shutdown (which causes an invalid memory access). This particular binding isn't ideal, is brittle, and will be an issue for anything doing the polling. Resolving #7457 should mitigate this issue. Backends are now _required_ to call `disconnect` in their destructor.
