[tilelink2] Convert TileLink2 to use IrrevocableIO. Add checks to the Monitor to enforce Irrevocable semantics on TLEdges. Update the RegisterRouterTests to pass the new Monitor assertions.

This case should result in undefined data for the Get.
It was previously requiring the Get to return the new Put data,
which is only guaranteed by a FIFO device.
