0d2ea14ac1 types: fix various use of volatile in type registration
The use of volatile was incorrect in GLib and has been that way for
a long time. Recently however that has changed, and this makes GTK
follow suit to avoid using volatile in the type registration.

See also: https://gitlab.gnome.org/GNOME/glib/-/merge_requests/1719

Combined with the above merge request for GLib, this fixes a large
number of compilation warnings when using Clang.

48dcbf4935 expression: Fix property expressions for interfaces
We were not checking the passed-in type in the right
way. An interface type can still pass the
g_type_is_a (..., G_TYPE_OBJECT) check, if G_TYPE_OBJECT
is one of its prerequisites. What we need to check is
whether the fundamental type is G_TYPE_OBJECT.

595cc929e6 Annotate the expression array as "nullable"
While it's a bit dubious whether array+length annotations should be
marked as "nullable", we do this elsewhere in the API, so might as well
be consistent.

In practice, the array argument is only ever allowed to be NULL iff the
length argument is 0; annotations are static, so if somebody decides to
pass a NULL argument with a non-zero value, they will get a run time
critical error, instead of a compile time one, which is somewhat counter
to the point of annotating the API in the first place.

Fixes: #2923

1375fb4464 Change button hierarchy
A radiobutton without indicator is really just a togglebutton with a
group.

A radiobutton with indicator is really just a checkbutton with a group.

Make checkbutton its own widget not inheriting from GtkButton.
GtkRadioButton could be removed but it stays for now.

Radiobutton && !draw-indicator => Togglebutton
Checkbutton && !draw-indicator => Togglebutton

Radiobutton && draw-indicator => CheckButton + group

In many cases, these were references to no longer
existing api, so some rewording was necessary.

24d6a190af Add pre-condition check on nullable argument
Even if `gtk_expression_watch()` will do the same, we're calling public
API, so we should perform a check at the point of use, to ensure that
warnings are easily debuggable.

6a4b5ead86 Annotate nullable argument
The `this_` argument is passed to `gtk_expression_watch()`, which
accepts it as nullable.

8daaafc864 Document how to define properties using GtkExpression
Use the GtkParamSpecExpression type to describe the property, and the
GValue API to set and get the expression instance.

ebaa96c0fa Turn GtkExpression into a GTypeInstance
Since it's a type with sub-classes, we need to use GTypeInstance (at the
very least), otherwise we won't be able to address each sub-class as
such.

This is similar to how GskRenderNode and GdkEvent are handled, with the
added difficulty that GtkExpression is meant to be used in properties,
in order to be deserialised by GtkBuilder. This requires adding a
GParamSpec sub-class that we can match on from within GtkBuilder,
alongside some convenience API for storing a GtkExpression inside a
GValue.

ad60efb5d7 expression: Invalidate bindings before destroying them
Use a weak ref to invalidate bindings. Make sure that this happens
before creating any watches, so that notifies from the
watched expression about changes will not trigger set_property() calls
during dispose()/finalize().

Invalidating also ensures that the watches aren't removed, which can
trigger warnings if the watches are watching the object itself, and the
weak refs cannot be removed anymore.

e9f1ee5aab Add GtkExpression
GtkExpressions allow looking up values from objects.

There are a few simple expressions, but the main one is the closure
expression that just calls a user-provided closure.
