A per frame tracker of sub-allocation out of a buffer, used to reduce the number of UBO objects we need to create.
This code is designed with one constraint in mind, that the lifetime of a sub-allocation is only for one frame and is discarded at the end of it, but also alive for the entire frame. This removes the need to free indivudial sub-allocation, or even track them beyond filling the UBO data and descriptor sets.
