mem: Snoop filter support for large systems
Changed SnoopMask to use std::bitset instead of uint64 so we can simulate
larger systems without having to workaround limitations on the number of
ports. No noticeable performance drop was observed after this change.
The size of the bitset is currently set to 256 which should fit most
needs.
