libcamera: properties: Add location property

Re-use the Control generation infrastructure to generate libcamera properties
and define the first 'Location' property.

Introduce three additional files:

- include/libcamera/property_ids.h
  Defines the properties ids

- src/libcamera/property_ids.cpp
  Defines the properties Control<> instances

- src/libcamera/property_ids.yaml
  Provide the first 'Location' property definition.
