docs: remove deprecated IE 9, 10, and IE mobile from docs (#38931)
In v10, framework support for IE 9, 10, and IE mobile was deprecated. In v11 we remove support for these browsers. This commit updates angular.io docs to exclude references to IE 9, 10, and IE mobile as well as polyfills that were needed to run Angular-based apps in these browsers. PR Close #38931

### IE 9, 10, and IE mobile support
|
||||
|
||||
Support for IE 9 and 10 has been deprecated, as well as support for IE Mobile. These will be dropped in a future version.
|
||||
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.
|
||||
|
||||
The final decision was made on three key points:
|
||||
* __Vendor support__: Microsoft dropped support of IE 9 and 10 on 1/12/16, meaning they no longer provide security updates or technical support. Additionally, Microsoft dropped support for Windows 10 Mobile in December 2019.
|
||||
* __Usage statistics__: We looked at usage trends for IE 9 and 10 (as well as IE Mobile) from various sources and all indicated that usage percentages were extremely small (fractions of 1%).
|
||||
* __Feedback from partners__: We also reached out to some of our Angular customers and none expressed concern about dropping IE 9, 10, nor IE Mobile support.
