[jdk22u] RFR: 8329823: RISC-V: Need to sync CPU features with related JVM flags

[Gui Cao]

Hi, The same issue also exists in the  jdk22u. I would like to backport [8329823](https://bugs.openjdk.org/browse/JDK-8329823) to jdk22u. With this backport,  We synchronize these features with related JVM flags so that "features" string can reflect actual usable CPU features.

### Testing

- [x]  Run tier1 tests on SOPHON SG2042 (release)

Results without specifying any jvm flags(After applying this patch)

----------System.out:(4/135)----------
WB.getCPUFeatures(): "rv64 i m a f d c"
CPUInfo.getAdditionalCPUInfo(): ""
CPUInfo.getFeatures(): [rv64, i, m, a, f, d, c]
TEST PASSE


Results with specifying -XX:-UseRVC (After applying this patch)

----------System.out:(4/130)----------
WB.getCPUFeatures(): "rv64 i m a f d"
CPUInfo.getAdditionalCPUInfo(): ""
CPUInfo.getFeatures(): [rv64, i, m, a, f, d]
TEST PASSED

Results with specifying -XX:+UseRVC (After applying this patch)

----------System.out:(4/135)----------
WB.getCPUFeatures(): "rv64 i m a f d c"
CPUInfo.getAdditionalCPUInfo(): ""
CPUInfo.getFeatures(): [rv64, i, m, a, f, d, c]
TEST PASSED
