RFR: 8279134: Fix Amazon copyright in various files

[Sergey Bylokhov]

This bug is similar to https://bugs.openjdk.java.net/browse/JDK-8244094

Currently, some of the files in the OpenJDK repo have Amazon copyright notices which are all slightly different and do not conform to Amazons preferred copyright notice which is simply (intentionally without copyright year):

"Copyright Amazon.com Inc. or its affiliates. All Rights Reserved."
