Subject: [PATCH] GameDB: Add patches for remaining KOF series

Fix for Depth precision.
Game fills upper 16bits of depth with 0xFFFF.
This results in a really high 32 bit value which is then converted to float because both hw and sw renderers lack double precision the lower 16 bits of the initial 32 bit value lose precision.

PAL : KOF2002+KOF2003
NTSC-J : NGBC+KOF2002+KOF2003
