ClassLoader.getResourceAsByteArray() was added for getting a versioned entry from a multi-release jar in JDK-8343427.

During CDS dump time when a ClassPathEntry is being created and a jar manifest is being processed, we can check if a jar file is a multi-release jar and store the info in the ClassPathEntry.

During runtime, only call ClassLoader.getResourceAsByteArray() if the jar file is a multi-release jar. This should reduce the number of java calls.
