gtk: Use new :checked state

gtk: Use new :checked state

on:
- GtkToggleButton
- GtkCheckButton
- GtkRadioButton
- GtkModelButton
- GtkCellRendererToggle
- GtkCheckMenuItem

also update themes:
- Adwaita
- Raleigh
but not the win32 theme.

The new :checked state replaces :active for the actual checkedness of
the widgets and :active is now used exclusively while the button is being
pressed.
