Sam James 2f24f10d9c libavcodec: fix -Wint-conversion in vulkan 
FIx warnings (soon to be errors in GCC 14, already so in Clang 15):
```
src/libavcodec/vulkan_av1.c: In function ‘vk_av1_create_params’:
src/libavcodec/vulkan_av1.c:183:43: error: initialization of ‘long long unsigned int’ from ‘void *’ makes integer from pointer without a cast [-Wint-conversion]
  183 |         .videoSessionParametersTemplate = NULL,
      |                                           ^~~~
src/libavcodec/vulkan_av1.c:183:43: note: (near initialization for ‘(anonymous).videoSessionParametersTemplate’)
```

Use Vulkan's VK_NULL_HANDLE instead of bare NULL.

Fix Trac ticket #10724.

Was reported downstream in Gentoo at https://bugs.gentoo.org/919067.
