Debugger/Memory: Add support for address spaces
Different address spaces can be chosen in the memory view panel. * Effective (or virtual): Probably the view people mostly want. Address translation goes through MMU. * Auxiliary: ARAM address space. Does not display anything in Wii mode. * Physical: Physical address space. Only supports mem1 and mem2 (wii mode) so far.
