8327743: JVM crash in hotspot/share/runtime/javaThread.cpp - failed: held monitor count should be equal to jni: 0 != 1

[shipilev]

Uncleanliness comes from JDK 21 not having JDK-8313882, so I had to rewrite the incoming hunks back to INT64_FORMAT and int64_t casts. This can be made clean by JDK-8313882 backport, but it has follow-up bugs that break Graal. It seems a better choice to just do a little deviation here.

Additional testing:

• MacOS AArch64 server fastdebug, new regression tests fail without the fix, pass with it
• Linux AArch64 server fastdebug, all
• Linux x86_64 server fastdebug, all
