RFR: 8180568: Refactor javax/crypto shell tests to plain java tests

[Sibabrata Sahoo]

This change is to remove the shell Test and convert to it's java equivalent. That is the reason the shell Tests are deleted and the equivalent Java implementation provided.
The purpose of the Test TestExemption.java is with limited crypto policy a JCE provider can supplemented additional crypto permissions through "cryptoPerms"  file bundled inside the JCE signed jar.
It also need to be noticed that TestExemption.java has '@requires java.runtime.name ~= "OpenJDK.*"'. It looks the intension of this Test availability in open GIT is to run by any other JDK providers.
