ffx_fsr3.cpp ffxFsr3ContextDestroy crash

[svatostop]

Hi! We are trying to integrate FSR3 to the project using sources from sdk/ folder.
We are running on Windows/Linux using Vulkan.

After trying to destroy FSR3 Context I had a crash in ffxFsr3ContextDestroy. From my investigation it was happening due to double freeing of backend interface which is trying to be used in ffxFsr3UpscalerContextDestroy.

Commenting out contextPrivate->backendInterfaceSharedResources.fpDestroyBackendContext(&contextPrivate->backendInterfaceSharedResources, contextPrivate->effectContextIdSharedResources); fix the issue

I run in a similar problem in ffx_frameinterpolation.cpp
At line 995 and 1002 FFX_FRAMEINTERPOLATION_RESOURCE_IDENTIFIER_PRESENT_BACKBUFFER is registered as dynamic resource, but in frameinterpolationRelease is not unregisted from the "resources not created internally"
Adding

context->srvResources[FFX_FRAMEINTERPOLATION_RESOURCE_IDENTIFIER_PRESENT_BACKBUFFER ]                      = {FFX_FRAMEINTERPOLATION_RESOURCE_IDENTIFIER_NULL};

at line 553 fixes the problem.
