Hardcode CEZ brick debris

See merge request STJr/SRB2Internal!247

If you wanted the game to reset the item selected to the top option like before though, I left a line commented out that would do that for you. Unlike the old item = 0 way, it would automatically be corrected for headers and other spaces (thus kind of future-proofing this code)

Also add a case for MT_BRICKDEBRIS to P_MobjThinker
