fix(packaging): remove polyfills needed to run tests on IE9 and IE 10 (#38931)

This commit removes polyfills that were needed to run tests on IE 9 and IE 10.

BREAKING CHANGE:

In v10, IE 9, 10, and IE mobile support was deprecated. In v11, Angular framework removes IE 9,
10, and IE mobile support completely.
Supporting outdated browsers like these increases bundle size, code complexity, and test load,
and also requires time and effort that could be spent on improvements to the framework.
For example, fixing issues can be more difficult, as a straightforward fix for modern browsers
could break old ones that have quirks due to not receiving updates from vendors.
