scripted-diff: rename ToStringIP[Port]() to ToStringAddr[Port]()

"IP" stands for "Internet Protocol".

"IP address" is sometimes shortened to just "IP" or "address".

However, Tor or I2P addresses are not "IP addresses", nor "IPs".

Thus, use "Addr" instead of "IP" for addresses that could be IP, Tor or
I2P addresses:

`CService::ToStringIPPort()` -> `CService::ToStringAddrPort()`
`CNetAddr::ToStringIP()` -> `CNetAddr::ToStringAddr()`
