…tion/stubs for blit engine rotations in GPU

- Assumption here is that only texel (0, 0) is accessible. Inline with other pitch 0 operations.
- TODO: Verify pitch 0 does not advance in Y either

- Figured out why it breaks things, ofc can't actually check for coverage when there is no proper fbo data persistence

- Properly wait for the buffer transfer operation to finish before map/readback!
- Change vkFence to vkEvent which works more like a GL fence which is what is needed.
- Implement supporting methods and functions
- Do not destroy fence by immediately waiting after copying to dma buffer

- The section needed starts at image origin, not transfer origin!

- Properly pass parameters such as rsx-pitch to the surface store
- Do not crash if a surface fails verification in flip, use fall-back instead

- Batch dma transfers whenever possible and do them in one go
- vk: Always ensure that queued dma transfers are visible to the GPU before they are needed by the host
  Requires a little refactoring to allow proper communication of the commandbuffer state
- vk: Code cleanup, the simplified mechanism makes it so that its not necessary to pass tons of args to methods
- vk: Fixup - do not forcefully do dma transfers on sections in an invalidation zone! They may have been speculated correctly already
