vk_memory_manager: Improve memory manager and its API
Fix a bug where the memory allocator could leave gaps between commits. To fix this the allocation algorithm was reworked, although it's still short in number of lines of code. Rework the allocation API to self-contained movable objects instead of naively using an unique_ptr to do the job for us. Remove the VK prefix.
