chore(build): use ESBuild as alternative build for Salesforce (#911)

- assign jQuery to the window object so that we can bundle jQuery in the same slickgrid bundle, in other words we would only have 1 single static resource (zip) for the entire slickgrid-universal and that's it (since everything is bundled, jQuery and even SortableJS also become part of the bundle and aren't needed as extra resources)
