RFR: 8251999: remove usage of PropertyResolvingWrapper in vmTestbase/nsk/aod

[Igor Ignatyev]

the patch
- removes `PropertyResolvingWrapper` from `vmTestbase/nsk/aod` tests
- updates `AODRunnerArgParser` to remove surrounding `"` symbols from `javaOpts` option values
- updates vmTestbase/nsk/aod test descriptions to have `"` in `javaOpts` values (as opposed of around `-javaOpts=$value`
  as it's now)
- mechanically reformats/cleans up the tests (whitespaces, imports, etc)

testing:
* [x] vmTestbase/nsk/aod on  {macosx,windows,linux}-x64
* [ ] vmTestbase/nsk/aod on macosx-x64 w/ `VM_OPTIONS`, `JAVA_OPTIONS` being empty and having value
