[ChannelFHawk] Expose scratchpad registers as a memory domain 

This more or less acts like memory for the ChannelF in practice, due to the actual console lacking RAM. Using debugger apis is very annoying for peeking at these registers and of course you can't just use RAM Watch or the Hex Editor with it locked to debugger apis
