Adds a VTCM Memory Pool class, which allocates the largest contiguous buffer possible within 1 page upon construction. Allocations and free space are maintained in two lists. Buffers that align on 2k size boundaries will choose the smallest open buffer which will satisfy the request. Non-aligned buffers will be allocated from the end of the free space. HexagonBuffer will use this pool to service VTCM scope requests, replacing the individual calls to allocated the memory on separate pages. The pool is created and destroyed in the device API Acquire/ReleaseResources. Adds unit tests to exercise edge cases.
