macOS: Don't clip menu item drawing to bounding rect when using CoreText
The bounding rect was computed based on the font metrics HarfBuzz gave us, but those may not be 1:1 with what CoreText ends up using. When that happens, drawInRect: will line-break the last word, which makes it fall completely outside of the single line bounding rect. This is not a good failure mode, so we prefer to draw the text at a point instead, allowing the resulting text to draw slightly outside of the bounding rect. This is preferable to adding a random padding to the width and hoping it will be enough to solve the problem.
