libcamera: media_object: Expose entity type

Browse Source 
Add a new field to the MediaEntity class to identify the type of
interface it exposes to userspace. The MediaEntity constructor is
changed to take a media_v2_interface pointer instead of just the device
node major and minor to have access to the interface type.
