Debugger: Fixed bug that copied watch entries from rom to rom

GBA: Fixed problem with wave channel in Kidou Senshi Gundam - Seed Destiny
...
Wave channel was playing the wrong audio on the title screen, because some writes were being blocked.
It looks like the restriction on wave "ram" access that exists on GB don't exist on GBA
Additionally, it seems like the wave data is supposed to be stored in a large shift register (not emulated yet), rather than an array of bytes

Debugger: Fixed issues with NES/SNES/PCE assemblers
...
-Labels defined within the assembler that were referred to before their definition did not work properly and ended up being assigned the wrong value (when the label's address wasn't a value between 0x100 and 0xFFFF) - this is fixed by running multiple passes until the resulting byte code stops changing.
-Fixed issues where e.g EOR $00, Y would be assembled as a 2-byte instruction, which is invalid.
