Added app mode support for micorsoft edge, IE mode for internet explorer and increase timeout for test run.

[Meenapintu]

Added MSIE mode to support device which does not have edge installed by default ( win <10).

Added support in edge to support edge mode or new window mode if app mode is not requested

tux test timeout updated as windows on GA was always failing with timeout.

I wonder what that one-off setup that Windows apparently needs to do is 🤔

Thanks for this update - nice to have the Windows test passing again, and the MSIE support has been requested for a long time, too 🙏
