GTAO console command minor issues

The following ambient occlusion console commands have issues:

r.AmbientOcclusion.Compute ?
The help text state it only works console but it also works on PC and likely other platforms.

r.GTAO.UseNormals ?
The default is 0 but the help text states 1 is default

r.GTAO.Combined
This console variable is not used in c++ and does nothing (the code that used this was removed in CL#9888089)

1. run the console command r.AmbientOcclusion.Compute ?
2. run the console command r.GTAO.UseNormals ?
3. run the console command r.GTAO.Combined 0

Expected
The help text is accurate and the commands do something

Actual
The help text for the first two commands are not accurate and the third command does nothing.
