Inventory: Add Decorator.Dimension interface

Inventory items can report their dimensions (if applicable and
if specified by the manufacturer) via management APIs like Redfish.

For this purpose, this commit introduces a Decorator.Dimension
interface containing the following properties:

1. Height - The height of the item in meters.
2. Width - The width of the item in meters.
3. Depth - The depth of the item in meters.
