RFR: 8191138: Remove deprecated java.security.acl APIs

[Sean Mullan]

Please review this change to remove the deprecated java.security.acl 
APIs. These APIs have long had a warning in the javadocs (since at least 
JDK 1.3.1 and possibly earlier) indicating that they were superseded by 
other APIs. They were initially deprecated in JDK 9 and marked for 
removal in JDK 10, so enough time has passed to allow for removal. 
Several external projects that were using the APIs have also either 
resolved the issues or have a plan to remove the dependencies.
