This patch adds the initial coexec scheduler scaffold for machine learning workloads on gfx1250. It introduces function and module-level controls for selecting the AMDGPU preRA and postRA schedulers, including an `amdgpu-workload-type` module flag that maps ML workloads to coexec preRA scheduling and a nop postRA scheduler by default. It also updates the coexec scheduler to use a simplified top-down candidate selection path that considers both available and pending queues through a single flow, setting up follow-on heuristic work.
