[lworld] RFR: 8373575: [lworld] Fix and problem list failing JDK, langtools and HotSpot tier 1 tests under --enable-preview [v7]

[Paul Hübner]

> Hi all,
> 
> Many tier 1 tests fail when running with `JTREG="JAVA_OPTIONS=--enable-preview"`. This PR does trivial fixes to test configurations and problemlists the rest of the failing tests.
> 
> This PR is necessary to complete [JDK-8371357](https://bugs.openjdk.org/browse/JDK-8371357).
> 
> Testing: tier1, with and without `--enable-preview`.
