gfxWindowsPlatform::GetGpuTimeSinceProcessStartInMs uses gdi32.dll, so should not be used when win32k is locked down.
The calls will fail and so they just cause lots of DLLs to be loaded unnecessarily.
In theory there shouldn't (hopefully can't) be any GPU usage in processes with win32k lockdown enabled.
