ipa: raspberrypi: Add frame_length to DeviceStatus

Browse source 
Store the frame length into the DeviceStatus struct. The value is extracted
from embedded data when available, or calculated from the VBLANK value passed
from DelayedControls otherwise.

Update imx477 and imx219 CamHelper classes to extract the frame length from the
embedded data buffer.
