MTP: Partial implementation of the GetObjectPropList command

In this initial implementation we only support fetching one property at a time.
Support depth = 0 (single object) or depth = 1 (all objects in a directory)
Reimplemented GetObjectPropValue on top of GetObjectPropList, since the former
is a special case of the latter.
