    igt/gem_ctx_switch: Measure qlen for timing loops

    Some platforms may execute the heavy workload very slowly, such that
    using a batch of 1024 takes tens of seconds and immediately overrunning
    the 5s timeout on a pass. Added up over a few dozen passes, this turns a
    120 second test into 10 minutes. Counter this by doing a warmup loop to
    estimate the appropriate queue len for timing.
