libcamera: control_serializer: Serialize info::def()
The ControlInfo class was originally designed to only transport
the control's minimum and maximum values which represent the control's
valid limits.
Later the default value of the control has been added to the ControlInfo
class, but the control serializer implementation has not been updated
accordingly.
This causes issues in IPA modules making use of ControlInfo::def() as,
when running in isolation, they would receive 0.
Fix that by serializing and deserializing the additional ControlValue
and update the protocol description accordingly.
