    drm/xe/uapi: Use hint for guc to set GT frequency
    
    Allow user to provide a low latency hint. When set,
    KMD sends a hint to GuC which results in special handling for that process.
    SLPC will ramp the GT frequency aggressively every time
    it switches to this process.
    
    We need to enable the use of SLPC Compute strategy during init, but
    it will apply only to processes that set this bit during process
    creation.
    
    Improvement with this approach as below:
    
    Before,
    
    :~$ NEOReadDebugKeys=1 EnableDirectSubmission=0 clpeak --kernel-latency
    Platform: Intel(R) OpenCL Graphics
      Device: Intel(R) Graphics [0xe20b]
        Driver version  : 24.52.0 (Linux x64)
        Compute units   : 160
        Clock frequency : 2850 MHz
        Kernel launch latency : 283.16 us
    
    After,
    
    :~$ NEOReadDebugKeys=1 EnableDirectSubmission=0 clpeak --kernel-latency
    Platform: Intel(R) OpenCL Graphics
      Device: Intel(R) Graphics [0xe20b]
        Driver version  : 24.52.0 (Linux x64)
        Compute units   : 160
        Clock frequency : 2850 MHz
    
        Kernel launch latency : 63.38 us

    v8(Vinay):
      - Add separate example for using low latency hint
    v7(Jose):
      - Update UMD PR
      - applicable to all gpus
    V6:
      - init flags, remove redundant flags check (MAuld)
    V5:
      - Move uapi doc to documentation and GuC ABI specific change (Rodrigo)
      - Modify logic to restrict exec queue flags (MAuld)
    V4:
      - To make it clear, dont use exec queue word (Vinay)
      - Correct typo in description of flag (Jose/Vinay)
      - rename set_strategy api and replace ctx with exec queue(Vinay)
      - Start with 0th bit to indentify user flags (Jose)
    V3:
      - Conver user flag to kernel internal flag and use (Oak)
      - Support query config for use to check kernel support (Jose)
      - Dont need to take runtime pm (Vinay)
    V2:
      - DRM_XE_EXEC_QUEUE_LOW_LATENCY_HINT 1 is already planned for other hint(Szymon)
      - Add motivation to description (Lucas)
