[Backport] [Oracle GraalVM] [GR-67842] Backport to 23.1: Espresso standalone with G1 gets stuck if there is an argument is not recognized.

[bulasevich]

Backports:

• [GR-67785] Fix detach_all_threads_and_tear_down_isolate. oracle/graal#11719

Conflicts:

• VMThreads.java merge conflict: if-block body changed on mainline.
• Resolution: updated the if-block condition manually.
• For reference, mainline commit 5fc4163 (missing in the GraalVM Community JDK 21u codebase) modified the if-block content
