bus/nes: Improved support for various VRC clone boards. (#8687)
* Expanded VRC4 CHR bank regs to 9-bit. This functionality is verified on Konami VRC4 hardware as well but is only used by clones (World Hero here).
* Removed board for World Hero. Its VRC4 clone chip is under a glop top but is thought to be identical to Konami's.
* Reimplemented TF1201 (Lethal Weapon) as a VRC4 subclass. Its clone chip is only known to differ by the IRQ reload bit, which it ignores.
* Reimplemented Shui Guan Pipe as a VRC4 subclass. Its clone chip has different PRG banking but is otherwise standard.
