8309841: Jarsigner should print a warning if an entry is removed

[wkia]

This is backport of "8309841: Jarsigner should print a warning if an entry is removed"

Original patch does not apply cleanly to jdk8:

• some minor conflicts in JDK code
• files moved to appropriate locations
• added the check in jdk/src/share/classes/sun/security/tools/jarsigner/Main.java at line 1196

in tests:

• ed25519 algorithm was replaced with RSA in RemovedFiles.java
• JarEntry copyEntry() procedure was manually added to JarUtils.java to make JarUtilsTest working.
• the tests were adapted to Java 8, including replaced Path.of, Files.writeString, package names, and arrays processing as well.

We need this fix in jdk8, as all versions have this issue with jarsigner.

New tests successfully ran locally on Linux, x86_64.
