winsys/radeon: add an interface for contexts
Same idea as in libdrm_amdgpu. A command stream can only be created for a specific context and it's always submitted to that context. This will mainly be used by amdgpu and it's required by the GPU reset status query too. (radeon only has a basic version of the query and thus doesn't need this) Reviewed-by: Christian König <christian.koenig@amd.com>
