8279487: riscv: Fix bad AD file when UseRVB is disabled

[feilongjiang]

After JDK-8279344, test/hotspot/jtreg/compiler/intrinsics/TestRotate.java will report bad AD file error in fastdebug when UseRVB is disabled.
Some match rules for RotateRight and RotateLeft are added by JDK-8279344 , which is under predicate of UseRVB. But match_rule_supported(Op_RotateRight/Op_RotateLeft) still returns true even when UseRVB is disabled. This will cause the bad AD file error on fastdebug JDK.
This PR fixes this issue by setting match_rule_supported(Op_RotateRight) and match_rule_supported(Op_RotateLeft) to false when UseRVB is disabled.

test/hotspot/jtreg/compiler/intrinsics/TestRotate.java passed with/without UseRVB on fastdebug JDK.
