KVM: TDX: Add macro to retry SEAMCALLs when forcing vCPUs out of guest
Add a macro to handle kicking vCPUs out of the guest and retrying
SEAMCALLs on TDX_OPERAND_BUSY instead of providing small helpers to be
used by each SEAMCALL. Wrapping the SEAMCALLs in a macro makes it a
little harder to tease out which SEAMCALL is being made, but
significantly reduces the amount of copy+paste code, and makes it all but
impossible to leave an elevated wait_for_sept_zap.
