[jdk21u] RFR: 8316880: AArch64: "stop: Header is not fast-locked" with -XX:-UseLSE since JDK-8315880 [v2]

[Aleksey Shipilev]

> Clean backport to fix a JVM bug, easily reproducible with `-UseLSE` with `LockingMode=2`.
> 
> Additional testing:
>  - [x] macos-aarch64-server-fastdebug build without the fix fails with `-UseLSE LockingMode=2`, passes with it
>  - [x] linux-aarch64-server-fastdebug, `tier1 tier2 tier3`
