[PATCH v1] ipa: mojom: Add sensor ID to IPACameraSensorInfo

[Celine Laurencin]

The sensor ID may be required from IPA to be able to select
specific tuning which can differ between sensors of the same model.
For instance, sensors from the same model may have different lens for
which different tuning is required.

Hence this patch provides the sensor ID part of the image sensor
characteristics IPACameraSensorInfo as defined in core.mojom IPA
interface.
