RFR: 8360164: AOT cache creation crashes in ~ThreadTotalCPUTimeClosure() [v4]

[Ioi Lam]

> `java -XX:AOTMode=create` calls `vm_exit(0)` to terminate the JVM (see [this e-mail thread](https://mail.openjdk.org/pipermail/hotspot-runtime-dev/2024-August/072122.html) for the reason for doing so). However, at this point, the JVM has executed quite a lot of Java code and there are many threads in the JVM that would require a proper shutdown. See [comments by @kimbarrett](https://bugs.openjdk.org/browse/JDK-8360164?focusedId=14792754&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14792754) for a detailed analysis.
> 
> This fix calls `JVM_Halt(0)` instead of `vm_exit(0)` so that the proper shutdown code is executed.
