ipa: mojom: Move CameraSensorInfo struct exclusively to IPA IPC

CameraSensorInfo structure is designed to pass in camera sensor related
information from pipeline-handler to IPA. Since the pipeline-handler
and IPA are connected via mojom IPC IPA interface, the interface
itself provides a more suitable placement of CameraSensorInfo,
instead of camera_sensor.h (which is a libcamera internal header
ultimately, at this point).

As CameraSensorInfo is already defined in core.mojom, it is just
a matter of removing [skipHeader] tag to allow code-generation
of CameraSensorInfo.

Finally, update header paths to include CameraSensorInfo definition
from IPA interfaces instead of "libcamera/internal/camera_sensor.h".
