RFR 8073423: Remove LazyClassPathEntry support if no longer needed

[harold seigel]

Hi,

Please review this change to remove LazyClassPathEntry support from the 
JVM.  With the demise of rt.jar, this is no longer used.

Open webrev: http://cr.openjdk.java.net/~hseigel/bug_8073423/

JBS Bug: https://bugs.openjdk.java.net/browse/JDK-8073423

The change was tested with JCK lang, vm, and api tests, hotspot jtreg 
tests, and testbase split_verifier and quick tests. Additionally, I 
tested '$JAVA_HOME/bin/java -XX:+LazyBootClassLoader -version" to test 
for the deprecation message for -XX:+LazyBootClassLoader.

  Thanks, Harold
