RFR: 8326100: DeflaterDictionaryTests should use Deflater.getBytesWritten instead of Deflater.getTotalOut

[Eirik Bjørsnøs]

Please review this test-only cleanup PR in preparation for deprecating `Deflater.getTotalOut()` in JDK-8326096.

This PR replaces various calls in`test/jdk/java/util/zip/DeflaterDictionaryTests.java` to `Deflater.getTotalOut()` when formatting some debugging output lines. 

Additionally, various debug output lines claim to print the result of calling `Deflater.getAdler`, but instead prints the output of `Deflater.getTotalOut'. This PR fixes this to print the actual Adler value instead.

Testing and verification: This is a test-only fix affecting only debug output. I have added the `noreg-self` label to the issue.
