[lilliput-jdk17u:lilliput] RFR: 8317452: [JVMCI] Export symbols used by lightweight locking to JVMCI compilers.

Mon Apr 8 17:11:16 UTC 2024

Backport of https://github.com/openjdk/jdk/commit/9718f490fb76f6712ac8f9c7f5248ca10bf83e6f

Eases subsequent backports and makes JVMCI compatible with future Graal LW locking impl.

Unclean because of context diff in vmStructs_jvmci.cpp, otherwise straightforward.
