Fix screen readers not indicating the emoji picker search field is focused. (#31128)
* Only set active descendant when the user starts typing.

* Fix jest tests.

* Remove aria-hidden

It was failing code quality checks and it actually wasn't addressing the issue.

* Only show highlight on arrow key navigation or updating the search query.

* Update screenshots

* Enter should not select an emoji if it is not highlighted.

* On clearing a query and using arrow kets again the highlighted emoji should be reset to the first.

* Update selector in picker tests
