drm/i915/xehp: CCS should use RCS setup functions
The compute engine handles the same commands the render engine can (except 3D pipeline), so it makes sense that CCS is more similar to RCS than non-render engines. The CCS context state (lrc) is also similar to the render one, so reuse it. Note that the compute engine has its own CTX_R_PWR_CLK_STATE register. In order to avoid having multiple RCS && CCS checks, add the following engine flag: - I915_ENGINE_HAS_RCS_REG_STATE - use the render (larger) reg state ctx.
