This should be moved to the test library. under `test/jdk/lib/testlibrary`.  I don't see an obvious generic home there yet, so I would suggest adding a `Utils.java`.  Other non-SSL test code may need this in future backports.

Note that by moving `ByteBuffer.slice` to a `Utils.java` (currently under `/test/lib`) the side effect is that tests that extend `SSLEngineTemplate`  must add the following JTReg stanza:


 * @library /test/lib
 * @build jdk.test.lib.Utils
 ```

To be able to compile classes that  `extend SSLEngineTemplate`, even though the test doesn't use the `slice` method, e.g. `test/jdk/javax/net/ssl/ALPN/SSLEngineAlpnTest.java`.
