External Libraries: Update the jQuery UI library to version 1.14.2.

In order to lower the risk with this change, jQuery UI is set to be in back compat mode to keep support for the jQuery UI 1.11 API.

The build for `core.js` is https://jqueryui.com/download/#!version=1.14.2&components=111111111111000000000000000000000000000000000000 with the addition of the deprecated $.ui.plugin from https://github.com/jquery/jquery-ui/blob/1.14.2/ui/plugin.js. All other files are based off of files in https://github.com/jquery/jquery-ui/tree/1.14.2/ui.

Developed in: WordPress#12526

Props pankaj.sakaria, mgol, mukesh27, ozgursar, siliconforks, joedolson, OllieJones, wildworks, jorbin.
Fixes #62757.
