GtkStyleContext will be deprecated in gtk 4.10.
https://docs.gtk.org/gtk4/class.StyleContext.html
This preserves code blocks where additional GtkStyleContext operations
were used, such as gtk_style_context_save/restore.
Fortunately for us GtkTreeView still operates pretty
much exactly like in GTK3. Other than that, it's a
dense junction of all that we've done so far to port
other panels.
For now, this patch only adds the context to the Resolution option to
disambiguate it from the display panel. This makes the code more complex
though, and will be changed again to add the context to all options
(making the strings identical to the ones in GTK+).
Fixes#394 for the printing panel
For an infinitesimal amount of time after opening the options dialog, a
spinner is displayed at the start of the action area while the dialog
loads asynchronously. Display the spinner in the center of the dialog
instead, using a GtkStack to switch between spinner mode and normal
mode. Test by removing the calls to printer_get_ppd_async(),
get_named_dest_async(), and get_ipp_attributes_async() from the bottom
of populate_options().
Why? (1) It looks better this way. (2) Need to stop using the action
area in order to switch to a header bar.

The update of alignment padding is not needed since gtk+ 3.14.
It was needed for proper alignment of widgets of action area
with those from content area.

Add Options dialog which allows users to set more options than current dialog.
The dialog reads printer's PPD file and add its options to the dialog together
with some preselected IPP options (#678637).
All operations in the dialog are asynchronous.
During implementation of this, the option for setting allowed users was removed
because this is not suitable for this panel (the option is intended for
administrators).
