Nowhere. You cannot freely enable any php version, Xampp 7.x comes with PHP7 and thats it, and there is neither any download tool for any message boards.
What do you understand by "Migrate phpBB 2.0 to wordpress"? phpBB is a sophisticated board script, wordpress is a sophisticated CMS (Content Managemant System). These are totally different tools, maybe there is a wordpress plugin which gives you the opportunity to install a board/forum script, but that would be with a totally different database, database model etc., there would not be any simple solution for converting the messages from phpBB to (whatever) wordpress forum/board.
I think there might be an option in WordPress to link it with an external script or domain (your phpBB forum), i.e. to embed a forum into WordPress, but i am not an WordPress expert and do not know much about it. What i know is the fact that a CMS is a CMS and a board is a board - like a car is a car and a TV is a TV. You cannot convert a car to a TV. So you cannot convert a board to a CMS.
