[jdk23u] RFR: 8341146: RISC-V: Unnecessary fences used for load-acquire in template interpreter

[Gui Cao]

Hi, The same issue also exists in the jdk23u. I would like to backport 8341146 to jdk23u. This is a risc-v specific change. Backport is clean, risk is low.

### Testing on SOPHON SG2042 (release) 
- [x] JCstress
- [x] Run tier1 tests
- [x] ~5% improvement on SPECJbb2005 score (-Xint -XX:+UseParallelGC)
