I changed some of to use this tag as part of other changes but didn't cover over the remaining tests that still use `@compile --enable-preview -source ${jdk.version} ...` and `@run main/othervm --enable-preview ...`.   I just scanned the tests in test/jdk/java/lang/Thread/virtual and they can all be changed the same way, if you want. If you leave it then we'll just change them at the next edit in this area.

I think I got most of those in the PR. There was a file or two I didn't update because not all the @compile/@run directives in the file used --enablePreview and the @enablePreview directive applies to all @compile and @run directives.
