* Fix SSR not reprojecting correctly and drifting on downsample, reference original code and backport some of the stuff from motion vectors too, major cleanup
* Logic for RenderTarget.GetTemporary probably shouldn't ceil, causes a lot of drifting in SSR even though the logic is correct, can see downsampling up to 10 and still remaining sharp

* Barriers are very strict on Intel ARC, make them explicit for SSAO and SSR, while at it make this logic for SSR simpler
For reference this is how it could appear on Intel ARC B580

* CommandList.ResourceBarrierTransition for Textures/RenderTargets
* Fix Reflections_GetHitPositionReprojection while being aware of Motion::Get for future Motion Vector API, deal with temporal stability better

* Build shader
* Format
* Re-enable CreateBLAS in RenderDeviceVulkan
* Update SPVRemapper to suppot raytracing opcode remapping
* Null initialize BLAS on RenderMesh
* Clean proper to generate BLAS on mesh data loading
* SceneRaytracingSystem stub
* Glue SceneRaytracing
* Remove pipelines from SceneRaytracing for now, just do TLAS, tie it to SceneRaytracingSystem, updates only once per frame just like how we want in a clean way

* Send Descriptor Set of Raytracing World to RenderAttribute
* RTAO example using RayQuery
* RayTracingShader API stub
* Set SM6.0 and dxlevel 120 as default
* Instead of making raytracing opt-in, add -nogpuraytracing to force disable it
* Add IRenderDevice::IsRayTracingSupported() to easily query support for it
* Fix IsRayTracingSupported()
* RTAO Adjustments
* Allow Rayquery through AS on Compute and Pixel shaders even if not optimal, avoids it crashing when acessing it on compute
* Strip CRaytraceSceneWorld to just generating TLAS, dont need anything else for now and we need a better way to handle UGC than what's there
* Bindless::RaytracingAccelerationStructure()
* Simplify interface too
* Stub for UpdateSkinnedForRaytracing
* Dotnet format and fix documentation, make RTAO run at correct stage
* Only support raytracing in tools mode for now
* Move raytracing stuff to Raytracing.hlsl
* Stub RTX shader
* Internal Raytracingshader and remove useless stuff exposed from it
* VfxProgramHasRenderShader should check for VFX_PROGRAM_RTX too, that's the source from everything else failing
* Add arbitrary entry point support to shaders, needed as RTX shaders use [shader("XXX")] instead of MainXXX directly
* RenderTools::TraceRays API, preliminary implementation, RTAO uses RaytracingShader
* Make RT support internal, allow RT on game
* Remove RaytracedAmbientOcclusion, will be on scenestaging when ready
* Update engine/Sandbox.Engine/Systems/Render/RayTracingShader.cs

* Fix leaky swapchain when resizing on game mode and dispose of handle after usage
VideoRecorder would get a strong handle copy of the swapchain every frame and retain it, causing native to fail to shutdown the copies from it
Made usage of getting native swapchain consistent on managed on other stuff, doing it like this ensures GC properly disposes of the strong handles even not disposing explicitly
Remove now unused ScreenRecorder.def and ScreenshotService.def
There are still optimizations to swapchain I'd like to send on another commit, game is allocating way more swapchains than needed even without the leak, has two completely different paths depending if you are MSAA or not, this can all be much simpler

* Remove NativeLayerRenderTarget, was unused and fucked
* Keep it as an ITexture/HRenderTextureStrong in managed so we avoid IDisposable, ReadTextureAsync with ITexture
