Currently, swtpm TPM state file is removed when a transient domain is
powered off or undefined. When we store TPM state on a shared storage
such as NFS and use transient domain, TPM states should be kept as it is.
Add per-TPM emulator option `persistent_sate` for keeping TPM state.
This option only works for the emulator type backend and looks as follows:
<tpm model='tpm-tis'>
<backend type='emulator' persistent_state='yes'/>
</tpm>
