[Mac] Fix bubble anchors in RTL

Previously, Bubble decoration and subclasses used slightly different
code to calculate where the image *should* be drawn, and where it was
drawn in practice. This change unites that code and removes code that
compensated for the difference.

The change in ContentSettingsBubble isn't RTL specific and fixes a
general regression (content settings bubbles in Canary are anchored
too far to the right.)
