Summary Measure glyphs in a single CoreText call rather than repeated calls

Rather than calling `CTFontGetBoundingRectsForGlyphs` once for each glyph (and passing a single `CGRect` to get the size), collect all glyphs needing measurement and ask for the entire set to be done at once. In theory, this will avoid the repeated work of creating graphics contexts, selecting a specific font face into it, transforming, etc., before making the measurement.
