DolphinQt: Remove Presets from GameConfigEdit

Back in 2018, a Presets system was added to DolphinQt's GameConfigEdit.
Presets was a dropdown menu where you could select a particular setting
to add to your custom game INI. Only a small number of settings were
made available, with the intent that more would be added over time.

8 years later, the set of available settings hasn't been expanded at
all, and I don't know of anyone who uses these presets. On top of this,
we have now made good progress in exposing per-game settings
graphically. I think the Presets system is best off removed.

In place of the Presets menu, we now have "Refresh" and "Open in
External Editor" buttons. These more useful actions were previously
hidden away in the Presets menu.
