JDK-8046070 - Class Data Sharing clean up and refactoring
Description
We currently have this flag just for running unit tests, etc:

  diagnostic(ccstr, SharedArchiveFile, NULL,                                \
          "Override the default location of the CDS archive file")          \

However, as part of the CDS enhancement work (see JDK-8046070), this should be changed into a product flag so that it can be used for normal usage scenarios, without having to specify -XX:+UnlockDiagnosticVMOptions.


The SharedArchiveFile will remain as diagnostic option, however we will add new API for unlocking a specific diagnostic flag:

  unlock_diagnostic()
