Add UpdateStatus reporter to packetbeat runners

[fearful-symmetry]

Proposed commit message

Closes #44655

This adds a StatusReporter to the packetbeat runner interface. Two things to note here:

1. I wasn't a fan of how we called Create() and SetStatusReporter() as two separate steps, as it means we don't get a StatusReporter object until after the initialization is complete. I added a CreateWithReporter interface to get around this, so we can set Configuring state at the proper time. If there's a reason why we don't want this, please tell me.
2. This is a very simple PR, as packetbeat doesn't have modules/metricsets like other beats, so we're just setting statuses on Configure and Start/Error/Stop for the overall packetbeat runner.

Tested in elastic-cloud 9.2.0.
