drm/msm/adreno: Expose a PARAM to check AQE support
AQE (Applicaton Qrisc Engine) is required to support VK ray-pipeline. Two
conditions should be met to use this HW:
1. AQE firmware should be loaded and programmed
2. Preemption support
Expose a new MSM_PARAM to allow userspace to query its support.
