[jdk11u-dev] RFR: 8268464: Remove dependancy of TestHttpsServer, HttpTransaction, HttpCallback from open/test/jdk/sun/net/www/protocol/https/ tests

[luchenlin]

I backport this for parity with 11.0.21-oracle.
test/jdk/sun/net/www/protocol/https/ChunkedOutputStream.java
'InetAddress loopback = InetAddress.getLoopbackAddress();' is added because it's miss.
test/jdk/sun/net/www/protocol/https/HttpsURLConnection/B6216082.java
Resolved due to context. Copyright
