[vulkan] Create a staging buffer struct And move the barrier prefabs into a more convenient place.

#ifndef __QF_Vulkan_barrier_h
#define __QF_Vulkan_barrier_h
[vulkan] Make some headers order-indepenedent In that they don't need Vulkan/qf_vid.h included first.

[vulkan] Add a couple of staging helper functions I got tired of writing the same 13 or so lines of code over and over (it actually put me off experimenting with Vulkan). Thus... QFV_PacketCopyBuffer does the work of handling barriers and a (full packet) copy from the staging buffer to a GPU buffer. QFV_PacketCopyImage does a similar job, but for images. However, it still needs a lot of work, but it does make getting a basic texture onto the GPU much less of a hassle. Both functions should make staging data much less error-prone.

[vulkan] Clean up image barriers a bit Mostly, this gets the stage flags in with the barrier, but also adds a couple more barrier templates. It should make for slightly less verbose code, and one less opportunity for error (mismatched barrier/stages).

[vulkan] Use indexed initializers for barriers This will make maintaining the arrays much easier: no worries about getting things out of sync.
