KVM: TDX: Handle SMI request as !CONFIG_KVM_SMM
Handle SMI request as what KVM does for CONFIG_KVM_SMM=n, i.e. return
-ENOTTY, and add KVM_BUG_ON() to SMI related OPs for TD.
TDX doesn't support system-management mode (SMM) and system-management
interrupt (SMI) in guest TDs. Because guest state (vCPU state, memory
state) is protected, it must go through the TDX module APIs to change
guest state. However, the TDX module doesn't provide a way for VMM to
inject SMI into guest TD or a way for VMM to switch guest vCPU mode into
SMM.
MSR_IA32_SMBASE will not be emulated for TDX guest, -ENOTTY will be
returned when SMI is requested.
