i386/tdx: Disable PIC for TDX VMs
Legacy PIC (8259) cannot be supported for TDX VMs since TDX module
doesn't allow directly interrupt injection. Using posted interrupts
for the PIC is not a viable option as the guest BIOS/kernel will not
do EOI for PIC IRQs, i.e. will leave the vIRR bit set.
Hence disable PIC for TDX VMs and error out if user wants PIC.
