Follow the same approach as used for the toggle button family:
Keep the button element name for button-like rendering, and
use a distinct modelbutton name otherwise, and add a subnode
for the indicator with name check or radio.
The intention was that ::iconic indicates which representation is
preferred (text or icon). We fall back to the other representation
if one is missing.
Add a menu-name property and use it in a default implementation
of ::clicked to switch menus if we are inside a stack. This means
GtkModelButton is no longer entirely generic, but rather expects
to be used inside a GtkPopoverMenu. It still works in other contexts
too, of course.
Rename the "toggled" property to "active", since that is what
GtkActionHelper expects to update for check and radio actions.
Also make the property readable, since GtkActionHelper wants
to read it.
Some recent refactoring changed things so that in_button is no
longer TRUE when released() is called for touch events. As a minimal
fix, let GtkButton do more of the work by chaining up to its
pressed and released handlers, which know how to handle touch
events. This could be further improved by leaving more of the
state handling to GtkButton, like it was done for GtkToggleButton.
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.

We were only setting the state transiently in ::draw, leading
to various drawing anomalies, such as labels not picking up
the appropriate color from BUTTON styles.
In iconic mode, model buttons will be styled like regular icon
buttons, preferring to show only the icon if one is set, falling
back to showing the label.

This is not a great name to use in themes; instead, add the
menuitem class, so themes can use .button.menuitem for styles
that are specific to menuitem-like buttons.
Similar in spirit to GtkModelMenuItem, this private GtkButton subclass
can connect to a GtkMenuTrackerItem and present itself as either a
regular button, a check button, or a radio button. Activation and
state tracking is done through the GAction that is associated with
the menu tracker item.
