configuration: Simplify applying per-game settings

Originally, every time we add a per-game setting, we'd have to guard for
it when setting it on the global config, and use a specific function to
do it for the per-game config.

This moves the global check into the ApplyPerGameSetting function so
that we can use it for changing both the global and per-game states.
Less work for the programmer.
