perf/x86/intel: Add ICL_FIXED_0_ADAPTIVE bit into INTEL_FIXED_BITS_MASK
ICL_FIXED_0_ADAPTIVE is missed to be added into INTEL_FIXED_BITS_MASK,
add it.
With help of this new INTEL_FIXED_BITS_MASK, intel_pmu_enable_fixed() can
be optimized. The old fixed counter control bits can be unconditionally
cleared with INTEL_FIXED_BITS_MASK and then set new control bits base on
new configuration.
