Jeroen Bakker 07ea6a5c23 Vulkan: Enable render graph
This PR hooks up the vulkan backend with the render graph
for drawing. It can run Blender better than the previous
implementation so we also flipped it to be the default
implementation.

**Some highlights**
- Adds support for framebuffer load/store operations
- Adds support for framebuffer subpass transitions
- Fixes workbench shadows
- Performance is just below OpenGL performance when comparing
  fps. But the screen feels more fluent when using complex
  scenes.
- Current performance is without doing any optimizations so
  will improve in the future.
- EEVEE will not crash but has artifacts and many parts that
  require more work.

**Related to**
- #121648
- #118330

**Known Limitation**
- Similar to previous implementation resources can be freed when
  still in use crashing Blender. This is typically the case when
  playing back an animation or updating a material icon.

**Next steps**
- Remove old implementation
- Get EEVEE to work
- Fix double resource freeing
- Improve performance by identifying hotspots and change them
