RFR: 8276787: Improve warning messages for -XX:+RecordDynamicDumpInfo [v2]

[Ioi Lam]

> [1] Fixed the error messages for the three scenarios described in the bug report. See the test SharedArchiveFileOption.java for new test cases for these messages.
> 
> [2] The global SharedDynamicArchivePath was used for both reading and writing the dynamic archive. Now the writing part is handled by DynamicArchiveBuilder::_archive_name. This simplifies the logic in Arguments::init_shared_archive_paths() and DynamicArchive::dump_for_jcmd(). It also makes the checks in [1] easier to implement.
> 
> Testing: running through Oracle CI tiers 1-4.
