RFR: 8372731: Detailed authentication failure messages [v2]

[Daniel Jeliński]

> Currently the HttpUrlConnection throws a generic "Authentication failure" exception when authentication fails locally.
> 
> The authentication may fail for various reasons like: incorrect server challenge message, unavailable encryption/digest algorithms, encoding errors etc. The detailed failure information should be available to the user. Without it, the exception is next to impossible to diagnose, see [JDK-8347778](https://bugs.openjdk.org/browse/JDK-8347778) for example.
> 
> This PR adds the original exception as the cause of the "Authentication failure" exception.
> 
> The detailed exception messages are enabled by the "hostInfo" and "hostInfoExclSocket" categories of "jdk.includeInExceptions". Note that "hostInfoExclSocket" is enabled by default.
> 
> Added a new test to verify that the exception details are present when jdk.includeInExceptions includes hostInfoExclSocket (default), and absent otherwise. Existing tier1-3 tests continue to pass.
