feat(core): add whole-machine save states with F5/F9 window slots

Browse source 
Machine::save_state and load_state encode the CPU, every RAM, and every device
through Snapshot impls into a versioned, checksummed format. Rejected loads leave
the machine unchanged. The ROM window saves to and loads from one state file
with F5 and F9.
