Subject: [PATCH 1/5] obs-ffmpeg: Make AMF encoder work on Linux
Only the fallback encoders are available (no texture support).
Requires AMD proprietary Vulkan driver, using different driver
will be detected on startup and the encoders disabled.

Subject: [PATCH 2/5] libobs-opengl: Enable imported dmabufs for rendering
For now just tag all imported images with GS_RENDER, this may not work
for some images that were produced by some hardware other than the gpu
render engines. But since we dont import vaapi decoded frames we
probably wont run into this. And we need this to render into vaapi
frames destined for encoding.

Subject: [PATCH 5/5] obs-ffmpeg: Implement Linux AMF texture encoding
v2: don't require vk_enum_string_helper.h
v3: only use one set of GL interop textures
v4: wait on Vulkan copy fence
v5: wait on GL copy sem + Vulkan external queue transfer
v6: use optimal tiling
v7: fix some validation errors
v8: init AMF context with our Vulkan device
