Patch pivots from using the `jt->is_interrupted(true)` to update the interrupt status of the interrupted waiting thread, to a new `jt->get_and_clear_interrupted()` which correctly propagates the interrupt status. Ran GHA Sanity Checks, local Tier 1 and 2, and new `hotspot/jtreg/serviceability/jvmti/vthread/InterruptRawMonitor` tests. Patch is clean.

Why is this worth backporting? You don't state the reason other than "it's a bug". This looks risky enough to not backport **without** a very good reason.
