[pygobject] Remove overrides for supporting pre-3.10 GObject signal functions

[Simon Feltman <sfeltman src gnome org>]

    Remove overrides for supporting pre-3.10 GObject signal functions
    
    Remove GObject override code for supporting pre-3.10 signal functions which
    annotate the object argument as "gpointer". With PyGObject 3.11 having a
    dependency on GObject 3.10, clear the special case overrides out.
