Add support for setting the peer verify name via the QNetwork* classes

This adds functions to QNetworkRequest to be able to set the
peerVerifyName. An overload of connectToHostEncrypted is also added to
have an extra argument to allow setting it directly in this manner too.

Fixes: QTBUG-73125

+    Initiates a connection to the host given by \a hostName at port \a port, using
+    \a sslConfiguration with \a peerName set to be the hostName used for certificate
+    validation. This function is useful to complete the TCP and SSL handshake
+    to a host before the HTTPS request is made, resulting in a lower network latency.
+
+    \note Preconnecting a SPDY connection can be done by calling setAllowedNextProtocols()
+    on \a sslConfiguration with QSslConfiguration::NextProtocolSpdy3_0 contained in
+    the list of allowed protocols. When using SPDY, one single connection per host is
+    enough, i.e. calling this method multiple times per host will not result in faster
+    network transactions.

+    \note This function has no possibility to report errors.
