Subject: [ui/ios] Add helper methods for getting the bounding size of some
 text.

These helpers are meant to ease the transition from the deprecated
|sizeWithFont:constrainedToSize:| methods. They'll also help reduce
boilerplate compared to the iOS method
|boundingRectWithSize:options:attributes:context:|

BUG=364419
