fix(ngAnimate): support removing classes from SVG elements when using jQuery

Fixes a regression in ngAnimate introduced in 2f4437b3, whereby SVG elements would not be able to
have classes removed by ngAnimate methods when jQuery was loaded (without also including libraries
which patch jQuery to support SVG elements, such as jquery-svgdom.js).

This fix exports jqLiteHasClass as a private method `$$hasClass` on the `angular` global object,
which enables ngAnimate to use this SVG-safe method for testing if the class is available.

fix(ngModelOptions): do not trigger digest on `setViewValue` if debouncing

Note that this change means that anyone watching `$viewValue` will have to
wait for a new digest before they are aware that it has been updated.
