[Chunk Uploads + Enum Refactors] Improve Chunk upload speed + Refactor MemoryTypes and VkQueues

[thr3343]

Cleans up significant boilerplate in several classes related to MemoryTypes + Queues, and replaces them with a much more readable and easier to use Enum-based system

This PR also corrects a mistake where cached system RAM was used instead of non-cached VRAM for Chunk uploads. Which slightly improves the speed of chunk loading and saving.
