res/res_pjsip_messaging.c: Fix: unstable domain filed in To header

This issue happens when client IP address changed like from wifi to 4G.
The domain filed in To header should be a fix string, this patch provide
a method of rewriting to a predefined domian string.

Usage: append ';x-to_domain=mydomain.com' to the end of full uri
which usually retrieved from ${PJSIP_DIAL_CONTACTS(${EXTEN})}
e.g.:
same => n,Set(ToContacts=${PJSIP_DIAL_CONTACTS(${EXTEN})})
same => n,While($["${SET(ToContact=${SHIFT(ToContacts,&):6})}" != ""])
same => n,Set(TOURI=pjsip:${ToContact}\;x-to_domain=mydomain.com)
same => n,MessageSend(${TOURI},${MESSAGE(from)})
