Ava UI: Reorder settings of Resolution Scaler

[AcK77]

This PR re-order the settings of the Resolution Scaler in Ava UI to follow what we currently have in GTK.

Before:

After:

I've sorted the configurations fields by their categories in LoadCurrentConfiguration and SaveSettings too. Some cleanup have to be done in a near future as those names suggest.

If possible, using Length - 1 instead of 4 is preferable. Then if we add more resolution scale presets (which will make the custom entry move down), we don't need to change that code.

Sadly it's not possible since we avoid to access of the view from the ViewModel, The value is a long and not an enum too, so I can't know the Length...
