RFR: 8356212: runtime/cds/appcds/LotsOfSyntheticClasses.java timed out with -XX:+AOTClassLinking [v2]

[Calvin Cheung]

> The LotsOfSyntheticClasses.java test times out intermittently when the `open/test/hotspot/jtreg:hotspot_aot_classlinking` test group is run with the` -XX:+AOTClassLinking` option on macosx-aarch64 platform.
> Increasing the timeout value from 500 to 800 seems to have addressed the issue.
> With the change, there's no timeout when the test group is run 40 times on macosx-aarch64 with the same option.
