[vala] Mark GObject *_get_type() functions as constant

[Jürg Billeter <juergbi src gnome org>]

commit fc7525d9c972feefe33de199ee9ae059115bf6f4
Author: Philip Withnall <philip withnall collabora co uk>
Date:   Tue Jun 22 14:42:54 2010 +0100

    Mark GObject *_get_type() functions as constant
    
    Add the G_GNUC_CONST attribute to the declarations of all *_get_type()
    functions, since they are constant functions.
    
    Fixes bug 622399.
