Introduced struct xe_spin_opts for xe_spin initialization,
adjusted tests to new xe_spin_init signature.

Extended spinner with fixed duration capability. It allows
to prepare fixed duration (ex. 10ms) workloads and take workloads/second
measurements, a handy utility for scheduling tests.

Basic test for xe_spin with fixed duration.

v2: - added asserts in div64_u64_round_up, duration_to_ctx_ticks,
      simplified loop_addr (Zbyszek)
    - added xe_spin_init_opts macro (Zbyszek)
    - corrected patch title (Kamil)
    - Added assert for expected spinner duration. (Zbyszek)
    A median of 5x100ms spins duration is computed, which should
    satisfy CI runs, although better accuracy is achieved with
    disabled logging (echo 0 > /sys/module/drm/parameters/debug).
