Add shared resource enumeration, provisioned range structure definition,
and provide a function to convert shared resource enums to their string
representation. These types will be used in a subsequent patch to read
VF provisioned resources from the debug filesystem.

Debugfs *_provisioned attributes carry also some additional data (e.g. number of ctxs or ggtt size) which is not covered here.
I understand it's not used by tests now, but assume this could be extended if there's such demand (e.g. some test needs it), right?
