RFR: 8247536: Support for pre-generated java.lang.invoke classes in CDS static archive [v14]

[Yumin Qi]

> This patch is reorganized after 8252725, which is separated from this patch to refactor jlink glugin code. The previous
> webrev with hg can be found at: http://cr.openjdk.java.net/~minqi/2020/8247536/webrev-05. With 8252725 integrated, the
> regeneration of holder classes is simply to call the new added GenerateJLIClassesHelper.cdsGenerateHolderClasses
> function.  Tests: tier1-4

Yumin Qi has updated the pull request incrementally with one additional commit since the last revision:

  Made isDumpingClassList a private final and add a public function to access it. Changed function validateInputLines to
  isValidInputLines and return a boolean to indicate its valid. Added more comments for review concern.
