Cheat bugfix and new A8 cheat type (#3328) 

* Bugfix for import and entering new cheats

Added needed g_emu_thread->reloadCheats calls after the reloadList() calls on entering a new code or importing new codes.

Without it I had to import new codes and then manually edit one of them for it to show up in the cheat counts and possibly even work

* Added Cheat Type A8

Added cheat type A8 which is the byte equivalent of the A7 cheat type as there will be a need of this type.

* Changed boolean parameters in last PR

Changed boolean parameters in last PR as per discord
