vlapic: refine IPI broadcast to support x2APIC mode

Browse Source 
According to SDM 10.6.1, if dest fields is 0xffU for register
ICR operation, that means the IPI is for broadcast.

According to SDM 10.12.9, 0xffffffffU of dest fields for x2APIC
means IPI is for broadcast.

We add new parameter to vlapic_calc_dest() to show whether the
dest is for broadcast. For IPI, we will set it according to
dest fields. For ioapic and MSI, we hardcode it to false because
no broadcast for ioapic and MSI.
