Added linux support for amf encoder through vulkan.
To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and
amf-amdgpu-pro package(amdgru-pro contains, but does not install automatically)
are required.
Initialization of amf encoder occurs in this order:
1) trying to initialize through dx11
2) trying to initialize through dx9
3) trying to initialize through vulkan
Only Vulkan initialization available on linux.
