silverwind a3977a3e51 fix webpack polyfills (#9735)
webpack polyfills did not work because useBuiltIns: 'entry' expects a
explicit core-js import. Changed it to 'usage' which does not require
these explicit imports and polyfills based on browserslist.

As a result, the built index.js now went from 128kB to 192kB.
