libcamera: controls: Use ControlIdMap in deserialization
Introduce a new field in the controls serialization protocol to
allow discerning which ControlIdMap a ControlInfoMap refers to.
The newly introduced IdMapType enumeration describes the possible
info maps:
- Either the globally available controls::controls and
properties::properties maps, which are valid across IPC boundaries
- A ControlIdMap created locally by the V4L2 device, which is not valid
across the IPC boundaries
At de-serialization time the idMapType field is inspected and
- If the idmap is a globally defined one, there's no need to create
new ControlId instances when populating the de-serialized
ControlInfoMap. Use the globally available map to retrieve the
ControlId reference and use it.
- If the idmap is a map only available locally, create a new ControlId
as it used to happen before this patch.
As a direct consequence, this change allows us to perform lookup by
ControlId reference on de-serialized ControlIdMap that refers to the
libcamera defined controls::controls and properties::properties.
