Debugger/Memory: Add support for address spaces

Browse Source 
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.
