configuration_shared: Initial functions and data for manual tristate

Sets up initial support for implementing colored tristate functions. These functions color a QWidget blue when it's overriding a global setting, and discolor it when not. The lack of color indicates it uses the global state, replacing the Qt::CheckState::PartiallyChecked state with the global state.
