> In preparation for when virtual threads can unmount while holding a monitor or unmount when blocking on monitorenter, the implementation of VirtualThread's interrupt method is refactored to avoid parking/blocking while holding the Thread's interrupt lock. The implementations of sun.nio.ch.Interruptible are refactored to close/wakeup the InterruptibleChannel/Selector after releasing the interrupt lock. There is a lot of test coverage for async close and interrupt, no additional tests are added.
