[RFC PATCH v1 10/23] libcamera: camera: Store `MetadataListPlan` in `Camera::Private`

[Barnabás Pőcze]

Just like `ControlInfoMap controlInfo_` is a public member of the private
camera data for pipeline handlers to populate, add a `MetadataListPlan` as
well for the pipeline handlers to fill. This will be used to initialize
the `MetadataList` of each request created by the camera.
