v3.7.7: More PPD fixes

Make PPD emulation use both namespaces instead, as KDE 6.3 uses the new one now and Gnome uses the old one. Then, fixup the AMD tdp controls to update ppd instantly to fix KDE updating lag, and unify the tdp value to ppd/energy controls to use the same map and update it so 18W devices work correctly with the tdp slider.
