    drm/xe/oa: Disallow OA from being enabled on active exec_queue's
    
    Enabling OA on an exec_queue toggles the OAC_CONTEXT_ENABLE bit in
    CTXT_SR_CTL register. Toggling this bit changes the size and layout of the
    underlying HW context image. Therefore, enabling OA on an already active
    exec_queue (as currently implemented in xe) is an invalid operation and can
    cause hangs. Therefore, disallow OA from being enabled on active
    exec_queue's (here, by active we mean a context on which submissions have
    previously happened).
    
    Transition from 1 -> 0 for this bit was disallowed in
    '0c8650b09a36 ("drm/xe/oa: Don't reset OAC_CONTEXT_ENABLE on OA stream
    close")'. Here we disallow the 0 -> 1 transition on active contexts.
    
    v2: Don't export exec_queue_enabled, define new xe_exec_queue_op (M Brost)
        Directly check OAC_CONTEXT_ENABLE bit from context image (J Cavitt)
