RFR: 8308236: Remove SystemDictionaryShared::clone_dumptime_tables() [v4]

[Ioi Lam]

> This function was necessary because we were patching the pointers inside `SystemDictionaryShared::_dumptime_table` when dumping the CDS archive. We no longer do that since [JDK-8307567](https://bugs.openjdk.org/browse/JDK-8307567), so this function and related code can be removed.

Ioi Lam has updated the pull request with a new target base due to a merge or a rebase. The incremental webrev excludes the unrelated changes brought in by the merge/rebase. The pull request contains four additional commits since the last revision:
