libcamera: ipu3: Fill stride and frameSize at config validation

Browse source 
Fill the stride and frameSize fields of the StreamConfiguration at
configuration validation time instead of at camera configuration time.
This allows applications to get the stride when trying a configuration
without modifying the active configuration of the camera.
