libcamera: v4l2_device: Return a unique pointer from fromEntityName()

The fromEntityName() function returns a pointer to a newly allocated
V4L2Device instance, which must be deleted by the caller. This opens the
door to memory leaks. Return a unique pointer instead, which conveys the
API semantics better than a sentence in the documentation.
