Miscellaneous updates to inventory interfaces

- Placed interfaces corresponding to physical items under
  Inventory/Item/ and interfaces which serve as item decorators under
  Inventory/Decorator/.
- Add some new dbus interfaces.
- Restructured Board item related interfaces such that there's a parent
  Board interface, and derivatives such as Motherboard, IO board, etc.
- Added new properties to existing interfaces.
