libcamera: pipeline: uvcvideo: Infer camera location from removable attribute
Use the removable attribute exposed by the USB device in sysfs to infer if the camera is an external (when removable) or front (when non-removable) camera. This is likely not perfect as the removable attribute is derived from ACPI data which may not always be accurate, and non-ACPI platforms likely report all devices as removable. Still, this is a first step upon which a better method could be built.
