Vulkan: Feedback loop detection and barriers (#7226)

Browse source 
* Vulkan: Feedback loop improvements

This PR allows the Vulkan backend to detect attachment feedback loops. These are currently used in the following ways:

- Partial use of VK_EXT_attachment_feedback_loop_layout
  - All renderable textures have AttachmentFeedbackLoopBitExt
  - Compile pipelines with Color/DepthStencil feedback loop flags when present
- Support using FragmentBarrier for feedback loops (fixes regressions from https://github.com/Ryujinx/Ryujinx/pull/7012 )

TODO:
- AMD GPUs may need layout transitions for it to properly allow textures to be used in feedback loops.
- Use dynamic state for feedback loops. The background pipeline will always miss since feedback loop state isn't known on the GPU project.
- How is the barrier dependency flag used? (DXVK just ignores it, there's no vulkan validation...)
- Improve subpass dependencies to fix validation errors

* Mark field readonly

* Add feedback loop dynamic state

* fix: add MoltenVK resolver workaround

fix: add MoltenVK resolver workaround

* Formatting

* Fix more complaints

* RADV dcc workaround

* Use dynamic state properly, cleanup.

* Use aspects flags in more places
