Remove usage of $.browser as it's unused and deprecated in jQuery. Fixes #14267

[jonathanKingston]

Description

Removed all usages of $.browser as the code appears to be old or unused.

Hashchange is now supported in IE9+ so there is no need for that library also.

As mentioned in #14173 (comment) swagger will likely be updated and made to be more modular so I ignored the file:

• app/code/Magento/Swagger/view/frontend/web/swagger-ui/js/lib/jquery.ba-bbq.min.js:

Fixed Issues (if relevant)

1. Migration of jQuery
2. Use of deprecated $.browser #14267

Manual testing scenarios

1. Ensure that step-navigator.js works as expected in IE/Firefox.
2. Ensure popup-window.js looks correct in IE.

The solution is ok. But travis build is failed. Please fix the code style. By our convention, we should use single quote mark.
window.addEventListener("hashchange", _.bind(stepNavigator.handleHash, stepNavigator));
