libcamera defaults all UVC cameras as 'external' (which makes sense
as there is not much information to accurately determine location).
However, in the HAL layer, we can probably determine accurately
by looking at HAL config file camera entries.

This series addresses the handling of such cameras, where the libcamera
reports properties::CameraLocationExternal, but we know one of the UVC
is internal/integrated to the system. It should be treated as internal.

Testing:
With nautilus, it has one UVC and one IPU3 cameras. With these patches
applied, both these cameras have id as '0' & '1' (i.e. internal).

With camera service still running, I hotplugged a external UVC camera,
and it got the camera numerical id as '1000'.
