amdgpu: Add new function to get fd.
Dual purpose: - The drm fd dedupe functionality confuses the radeonsi amdgpu winsys if radeonsi isn't the first thing opening the device. By exposing the fd we can detect this case. - For a common mesa Vulkan sync objects implementation with syncobj. (notable: no buffer allocation) Both shouldn't interferece with libdrm_amdgpu functionality though it does somewhat piece the abstraction of the library.
