The current UI have no live-check to check whether a VM connect to

So we add an assert to the schema and return error when user connect a
VM to itself.

`vm_name` is not the name of the vUART connection.
This message want to remind user the VM connected to it self, so I change the report-on to make it clear:

 12     <xs:annotation acrn:severity="error" acrn:report-on="$vuart_connection/endpoint">
 13       <xs:documentation>"{$vm_name}" can't connected to itself</xs:documentation>

Now the message is:

"ERROR:root:/acrn-config/hv/vuart_connections/vuart_connection[2]/endpoint[1], /acrn-config/hv/vuart_connections/vuart_connection[2]/endpoint[2]: "POST_RT_VM1" can't connected to itself"
