Add property "quote-generation-socket" to tdx-guest, which is a property
of type SocketAddress to specify Quote Generation Service(QGS).
On request of GetQuote, it connects to the QGS socket, read request
data from shared guest memory, send the request data to the QGS,
and store the response into shared guest memory, at last notify
TD guest by interrupt.
command line example:
qemu-system-x86_64 \
-object '{"qom-type":"tdx-guest","id":"tdx0","quote-generation-socket":{"type":"unix", "path":"/var/run/tdx-qgs/qgs.socket"}}' \
-machine confidential-guest-support=tdx0
Note, above example uses the unix socket. It can be other types, like vsock,
which depends on the implementation of QGS.
To avoid no response from QGS server, setup a timer for the transaction.
If timeout, make it an error and interrupt guest. Define the threshold of
time to 30s at present, maybe change to other value if not appropriate.
