a11y: Add gtk_accessible_text_get_extents

This will be used to implement GetRangeExtents in atspi.

The `XAccessibleText` UNO interface currently
only has a way to retrieve the extents of a
single character, so just return `false`
if the extents for a larger text range is
requested.
(LO's gtk3/ATK implemenation currently also doesn't
implement AtkText.get_range_extents` [1])

To actually work, this also needs changes on
GTK side to support non-GtkWidget GtkAccessible
implementations. Pending MR: [2]
