Hi,

Another foundation for 20H1 feature support and testing:

Is your feature request related to a problem? Please describe.

In Windows 10 build 18963, modern keyboard executable has been renamed to Text Input Host 9textinputhost.exe). Unlike initial version of modern keyboard, this name does not break Python's naming conventions and better describes what the app actually does.

Adding support for the renamed modern keyboard is needed to test 20H1 modern input features such as modern CJK IME and other possible enhancements.

Describe the solution you'd like

Add an app module for Text Input Host which is an alias for current modern keyboard app module. Work on modern keyboard will continue from the old module.

Describe alternatives you've considered

Leave it as is.

Additional context

This support is needed for 20H1 onwards.

Thanks.
