BF: fix an issue with etRecord component for Stop Only

[mh105]

There is a bug with the etRecord component in builder because the constructor for psychopy.hardware.eyetracker.EyetrackerControl always initializes the _status attribute as NOT_STARTED. This causes an issue when the component is used under the "Stop Only" Record actions. In this scenario, two independent etRecord components are initialized, causing the bug, because the experiment can only change the status of the second component (supposed to stop recording) to FINISHED if the status is already STARTED.

Instead, the status of any EyetrackerControl instance should reflect whether recording is currently enabled for the tracker instance passed into the constructor. Looking through psychopy.iohub.devices.eyetracker.hw, isRecordingEnabled() is appropriately defined for everyone so this fix should work seamlessly.

@RebeccaHirst @TEParsons this is an even shorter changed compared to your solutions in #6457 and #6456

Is this going to be sufficient for the short-term BF (postponing the other discussion about whether "start/stop" times refer to the start of the component versus the start of the eyetracker?

[TEParsons]

Yep sounds like a plan :) @mh105 would you mind creating a new branch from psychopy/release and cherry picking this change across? Then we can pull this in for the next bug fix release and continue working on the other stuff @RebeccaHirst and I are figuring out in the dev branch

[mh105]

Sure. Just created a new PR to psychopy/release. I'll close this now.
