Ford: add alert for steering wheel angle not ready (#28140)

* add event for steering angle calibrating

* how about this

how about this

* rename

* more openpilot-y

* add comment to code

* move to top

* better wording

* more general

* fix

* ?

* above

* bump cereal to master

* add more comms
