D3D/VK driver may return a size larger than requested and could cause
PowerOfTwo() to overflow. This change adds a check to ensure the size
is within the limit before attempting sub-allocation.

This mostly makes the MemoryAllocator not owned by the
BuddyResourceAllocator so that we don't need an extra class for the
dependency injection in the Vulkan backend. (the container for the
BuddyMemoryAllocator can be it's MemoryAllocator at the same time).
Also renames methods of MemoryAllocator to be more explicit.
Also renames the constructor parameter of BuddyMemoryAllocator to be
(subjectively) closer to what the represent.
