8283865: riscv: Break down -XX:+UseRVB into seperate options for each bitmanip extension

[zifeihan]

Hi, The same issue[1] also exists in the riscv-port-jdk11u. According to the spec, we need to break down UseRVB into two individual options UseZba and UseZbb to enable or disable Zba and Zbb respectively.

Linux RISCV64 release hotspot/jdk tier1 tests are passed on QEMU with following options:

• +UseZba && +UseZbb
• +UseZba && -UseZbb
• -UseZba && +UseZbb
