and from member methods of String.

Reviewed by Oliver Hunt.

Make 'numGraphemeClusters' & 'numCharactersInGraphemeClusters'
global function defined in PlatformString.h, rather than
member methods on String (these can be implemented purely
using the characters() and length() public interface),
and make 'makeCapitalized' a static function in RenderText.cpp.
