drm/amdgpu: Add command to override the context priority.
Given a master fd we can then override the priority of the context in another fd. Using these overrides was recommended by Christian instead of trying to submit from a master fd, and I am adding a way to override a single context instead of the entire process so we can only upgrade a single Vulkan queue and not effectively the entire process. Reused the flags field as it was checked to be 0 anyways, so nothing used it. This is source-incompatible (due to the name change), but ABI compatible.
