Subject: ipa: ipu3: Update camera controls in configure()

When a new CameraConfiguration is applied to the Camera the IPA is
configured as well, using the newly applied sensor configuration and its
updated V4L2 controls.

Also update the Camera controls at IPA::configure() time by re-computing
the controls::ExposureTime and controls::FrameDurationLimits limits and
update the controls on the pipeline handler side after having configured
the IPA.
