sega/sms.cpp: Refactored Game Gear handling. (#10682) Use a memory view to switching between Game Gear and Master System compatibility I/O space mapping. Got rid of most of the conditional code checking whether it's a Game Gear driver. Got rid of the special Game Gear EXT port slot. It's the same thing as a Mega Drive controller/expansion I/O port with a different connector. sega/mdioport.cpp: Added a variant for the Game Gear with the TH/PC6 interrupt latch, and added it to the Game Gear.
