RFR: 8365844: RISC-V: TestBadFormat.java fails when running without RVV

[Dingli Zhang]

Hi,
Can you help to review this patch? Thanks!

We noticed that testlibrary_tests/ir_framework/tests/TestBadFormat.java fails when running tier4 tests on p550.
The reason for the error is that the Vector test related to badVectorNodeSize requires RVV on riscv, otherwise the expected passing case will fail and cannot match FailCount.

### Test (fastdebug)
- [x] Run testlibrary_tests/ir_framework/tests/TestBadFormat.java on k1/k230/sg2042
