feat(jqLite): expose isolateScope() getter similar to scope()

See doc update in the diff for more info.

BREAKING CHANGE: jqLite#scope() does not return the isolate scope on the element
that triggered directive with isolate scope. Use jqLite#isolateScope() instead.

  * - `injector()` - retrieves the injector of the current element or its parent.

+ * - `isolateScope()` - retrieves an isolate {@link api/ng.$rootScope.Scope scope} if one is attached directly to the

+ *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
  * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
  *   parent element is reached.
