Some tests need this since they use vm.allThreads() to find the debuggee threads. Without includevirtualthreads=y, vm.allThreads() usually won't return any virtual threads (although it might return some for which events have been triggered).

There were about 350 tests that actually needed includevirtualthreads=y, but most of these have been addressed by other PRs, leaving the 20 or so tests being addressed in this PR. With this PR now defaulting to includevirtualthreads=n, the tests that require includevirtualthreads=y need to override the default by specifying the -includevirtualthreads @run option.
