libcamera: camera: Ensure correct id maps are always set

`Camera::Private::properties_` is a default constructed `ControlList`,
therefore it does not have an associated `ControlIdMap`. `controlInfo_`
is in a similar situation.

Extend the `Camera::Private` constructor to initialize the control id map
of both properly.

Multiple pipeline handlers copy the sensor's property list and
set that as camera properties, and since the `CameraSensor{Legacy,Raw}`
classes set the proper id map, the camera properties will have it too.

However, some pipelines, e.g. `uvcvideo` or `virtual`, do not do so,
and thus there will be no id map set. To fix this, extend the
`Camera::Private` constructor to set `properties::properties`.

As for `controlInfo_`, all pipeline handlers overwrite it during
camera initialization (and thus it will have the correct id map),
but still initialize the id map so that it is set at all times.
