[PBQP] Tidy up CostAllocator.h: fix variable case, rename CostPool to ValuePool.

Browse Source 
No functional change. This just brings things more in-line with coding
standards, and makes ValuePool's functionality clearer (it's not tied to pooling
costs, and we may want to use it to hold other things in the future).
