[jdk17u-dev] RFR: 8331405: Shenandoah: Optimize ShenandoahLock with TTAS

[Xiaolong Peng]

Hi, 
    This PR is a Backport of [JDK-8331405](https://bugs.openjdk.org/browse/JDK-8331405): Shenandoah: Optimize ShenandoahLock with TTAS, the original commit was authored by Aleksey Shipilev on 2 May 2024 and was reviewed by Zhengyu Gu and Y. S. Ramakrishna, and it had already been backported to jdk21.
    It is a clean merge w/o any conflicts, overall risk should be very minimal given it is single line change to apply TTAS. 

   Here is the series of improvements for ShenandoahLock I'm going to backport to JDK17:
