[lworld] RFR: 8328150: [lworld] Adjust flags to "--enable-preview" clear out EnableValhalla and EnablePrimitiveClasses [v3]

[David Simms]

> * Removed all cases of -XX: EnableValhalla and EnablePrimitiveClasses
> * Deleted tests that were dominated by now defunct concepts (withfield, entirely primitives classes etc)
> * Trival fixes to simply remove primitive class tests cases
> * `@ignores` tagged with bug number where tests need non-trival updating to JEP401 concepts
