[jdk13u-dev] RFR: 8279842: HTTPS Channel Binding support for Java GSS/Kerberos

[Olga Mikhaltsova]

It's backport of JDK-8279842 to jdk13u.

The original patch applied cleanly (commit 1) but it's required the following corrections similar to jdk11u:
1) Drop @java.io.Serial (ChannelBindingException.java) (commit 2);
2) Replacement of instanceof patterns (AbstractDelegateHttpsURLConnection.java, HttpsCB.java) (JEP 305, JDK 14) (commit 3);
3) Substitute callAs(..) with doAs(..) (HttpsCB.java) (JDK-8275529, JDK 18) (commit 3);
4) Add import java.security.PrivilegedExceptionAction (HttpsCB.java) (commit 3).

Tested on Linux x64, Windows x64, macOS x64 with the tests' groups: `test/jdk/sun/security/krb5` and `test/jdk/com/sun/jndi`, - with no regression. The included tests HttpsCB.java and LdapCBPropertiesTest.java passed successfully.
