- add M64P_MEM_FLAG_*_EMUONLY types to signify memory areas to which the emulated CPU may read or write, but the debugger cannot
- extended read_memory_32() in debugger/dbg_memory.c to be able to read from special memory blocks like RDRAMREG, RSPREG, RSP, DP, VI, AI, etc
- fixed byte order bugs in read_memory_32_unaligned() and write_memory_32_unaligned()
- extended get_memory_flags() in debugger/dbg_memory.c to return new flags and cover special memory spaces
