This change adds a new nine-patch asset for the location bar that
is used exclusively in the compositor. This allows us to have stop
drawing the location bar as part of the toolbar texture and draw it
with correct colors in the compositor. Since the new texture draws
the entire location bar instead of just part of it, the 'anonymize'
layer is not needed in the modern design (we can now simply draw
over the url). These changes correct all the toolbar/compositor
related animations.
