DiscardableHandle Implementation

This change adds a DiscardableHandle class, which acts as the primary
synchronization mechanism for the GPU Discardable Memory system.

This is the first in a sequence of CLs which implement the GPU
Discardable Memory system. This class is currently only created/used by
unit test code.
