I just wanted to know which type of checkmate is this called or is it even invented??


It looks like a ladder mate. But since there are three attacking pieces instead of two, no reason to force the opposing king to the side. One of the rooks was serving the same purpose as the edge of the board.

Another term for it other than ladder mate is lawnmower mate. Basically the same thing. Chessfox has a list of 36 of the most common checkmate patterns.

It's actually called an illegal position.
I agree. White may actually the winner. Black's king ran away.
