  -----------
  [AMDGPU][Attributor] Remove final update of waves-per-eu after the attributor run

We do not need this in the attributor, because `ST.getWavesPerEU` accounts for both the waves-per-eu and flat-workgroup-size attributes. If the waves-per-eu values are not valid, it drops them. In the attributor, we only need to propagate the values without using intermediate flat workgroup size values.
