[TextInput] Add TextInputType.webSearch (#15762) (#158323)

Browse Source 
This PR  adds `TextInputType.webSearch` that allows to show a keyboard with ready access to a "." key on iOS. On Android this is re-mapped to `url` which shows the same behaviour as `webSearch` on iOS. This fixes issue #157562.

There also is a [corresponding *engine* PR](https://github.com/flutter/engine/pull/56428).

Screenshot from iOS demo app:
