release_stages: Split Paygen -> Signing, Paygen stages.

This creates a SigningStage that must be run before the Paygen stage to
wait for signed images to be uploaded. This means that signing errors
are easily distinguished from Paygen errors on the waterfall.

The signing stage signals to Paygen with the board attribute
'signed_images_ready' as soon as all boards are signed and ready.

We don't start Paygen for any channels until all channels are
signed. And won't run Paygen for any channels if any channels get a
signing failure (which is a regression).
