qemu/apic: minimal MSI/MSI-X implementation for PC

Implement MSI support in APIC. Note that MSI and MMIO APIC registers
are at the same memory location, but actually not on the global bus: MSI
is on PCI bus, APIC is connected directly to the CPU. We map them on the
global bus at the same address which happens to work because MSI
registers are reserved in APIC MMIO and vice versa.
