Fix verilog key handling for player 2

[ewenmcneill]

Fix regression in handling of player 2 keys in the Verilog simulator, accidentally introduced by 271c2ea (they were inadvertently redirected to also control player 1).

Also update presets/verilog/switches.v documentation comment of what the keys are to match the keys actually used now across all platforms. (In particular Z and X seems to have been repurposed for player 1 gamepad use, rather than player 2 A/B buttons; player 2 A/B are now T and R.)
