Fixes for virtual threads:
src/hotspot/share/prims/unsafe.cpp
 - assert we don't get passed a virtual thread

src/hotspot/share/runtime/javaThread.cpp
 - augment thread dumps to show virtual thread stacks for debugging

src/java.base/share/classes/java/lang/Monitor.java
 - When dealing with virtual threads we have to pass the carrier to unparkMonitor
 - When updating the status of virtual threads we have to update the carrier's status
 - Fix doAwait() so that we always re-acquire the Monitor even if we throw an exception
 - Expand logging

src/java.base/share/classes/java/lang/Thread.java
 - Abort on lockStack access errors as we can't throw AIOOBE

src/java.base/share/classes/java/lang/VirtualThread.java
 - expose carrierThread to Monitor class
