##### Feature support
###### DXGI incremental presentation
Added basic support for DXGI [present parameters](https://learn.microsoft.com/en-us/windows/win32/api/dxgi1_2/ns-dxgi1_2-dxgi_present_parameters). This fixes UI rendering issues in **VirtualDJ** (#5853), and is also used by various game launchers, such as Ubisoft Connect.

If supported by the driver, `VK_KHR_incremental_present` is leveraged to forward dirty rectangles to Vulkan, which *may* reduce the amount of work the compositor has to do, but is not guaranteed to do so.

###### D3D11 buffer render targets
Implemented support for creating render target views on [buffers](https://learn.microsoft.com/en-us/windows/win32/api/d3d11/ns-d3d11-d3d11_buffer_rtv) directly. This is primarily used by various older Frostbite engine titles, including **Battlefield 3** where it fixes a long-standing issue with clouds misrendering in some situations (#5857).

**Note:** This feature is emulated by creating a 1D texture internally. It is *not* meant to be performant.

###### Intel vendor extensions
Intel-specific extension libraries are now loaded when using an Intel GPU, which is a requirement for Proton to support Intel vendor extensions for D3D11 in the future. This will work similarly to AMDAGS and NVAPI extensions that are already supported.

##### Bug fixes and Improvements
- Improved compatibility with some external overlays that hook specific DXGI entry points (PR #5846, PR #5851).
- Render areas in render passes are more aggressively optimized to the actual rendered image region on tiling GPUs.
- Fixed a D3D9 fog regression that broke rendering in **Mabinogi**, **The Witcher 1** and potentially other games. (#5804, #5808)
- Fixed a crash when applications try to compile shaders that can only work with D3D12.
- Worked around a specific type of out-of-memory crash on Nvidia GPUs with descriptor heaps enabled. (#5855)
  Additionally, added `dxvk.enableNvCudaInterop` configuration option so users can explicitly disable `VK_NVX_*` extensions. This may be helpful for troubleshooting similar out-of-memory errors, but disables DLSS support.
- **Ghost Recon Breakpoint**: Fixed an issue where pipeline state would not be set up properly for a specific shader.
  Also fixed an issue with water misrendering on Nvidia GPUs. (#5849, https://github.com/doitsujin/dxbc-spirv/pull/92)
- **Mirrors Edge**: Fixed some Vulkan validation errors. (#5826)
- **RaceRoom Racing Experience**: Fixed an issue where the web-based UI wouldn't render properly on Proton 11.
