This avoids some (not so noticable) overhead in The Finals from constantly scanning ntdll.dll from disk when NtConvertBetweenAuxiliaryCounterAndPerformanceCounter cannot be found (the function is not used).
The function always returns STATUS_NOT_SUPPORTED on my local Windows and Testbot machines so it is impossible to guess the parameters exactly. kernelbase functions are not needed but I added them to test that "not implemented" status is returned from those as well and not due to wrong Nt function call.
