From: Isaku Yamahata <isaku.yamahata@xxxxxxxxx>
Add a new bool member, eoi_intercept_unsupported, to X86MachineState with
default value false. Set true when tdx kvm type. Inability to intercept
eoi causes impossibility to emulate level triggered interrupt to be
re-injected when level is still kept active. which affects interrupt
controller emulation. Such new behavior will be introduced later.
