add new IRQBROADCAST for mce flags

A new mce flag IRQBROADCAST can help to simulate an IRQ broadcast,
which means when injecting one error, other cpu (CPU no error injected)
can working in IRQ context besides NMI context.
To distinguish the broadcast type, another parameter named NMIBROADCAST
is added, too.
