Drop gdk_pango_context_get_for_display

This api does not offer much over the pango api, and
the use of the resolution here is causing layering
problems.

* Creating a #PangoLayout object is the first step in rendering text,
* and requires getting a handle to a #PangoContext. For GTK+ programs,
* you’ll usually want to use gtk_widget_get_pango_context(), or
* gtk_widget_create_pango_layout(), rather than using the lowlevel
* gdk_pango_context_get_for_display(). Once you have a #PangoLayout, you
* can set the text and attributes of it with Pango functions like
* gtk_widget_create_pango_layout(). Once you have a #PangoLayout,
* you can set the text and attributes of it with Pango functions like
* pango_layout_set_text() and get its size with pango_layout_get_size().
* (Note that Pango uses a fixed point system internally, so converting
* between Pango units and pixels using [PANGO_SCALE][PANGO-SCALE-CAPS]

/**
* gdk_pango_context_get_for_display:
* @display: the #GdkDisplay for which the context is to be created
*
* Creates a #PangoContext for @display.
*
* The context must be freed when you’re finished with it.
*
* When using GTK+, normally you should use gtk_widget_get_pango_context()
* instead of this function, to get the appropriate context for
* the widget you intend to render text onto.
*
* The newly created context will have the default font options
* (see #cairo_font_options_t) for the display; if these options
* change it will not be updated. Using gtk_widget_get_pango_context()
* is more convenient if you want to keep a context around and track
* changes to the font rendering settings.
*
* Returns: (transfer full): a new #PangoContext for @display
*
* Since: 3.22
