Ensure homekit camera stream can be restarted after failure

[bdraco]

This change is much smaller than it appears as its based on #35299 which should go in before this PR

Proposed change

If ffmpeg failed to start, was killed, or the iOS device
closed the stream right away, the stream could never
be started until the HomeKit bridge was restarted.

Looks like there are multiple race conditions here. I think we need something to watch the pid every 10 seconds and see if it dies and then reset the camera state as this is only going to cover the case were ffmpeg dies right away.

probably async_track_interval and than cancel when it fails or streaming stops

Dead camera sessions are now getting cleaned up reliably.
