libcamera: ipa: Add support for CameraSensorInfo

Add support for camera sensor information in the libcamera IPA protocol.

Define a new 'struct ipa_sensor_info' structure in the IPA context and
use it to perform translation between the C and the C++ API.

Update the IPAInterface::configure() operation to accept a new
CameraSensorInfo parameter and port all users of that function to
the new interface.
