[PATCH] D118225: [RISCV] Decouple Zve* extensions.

kito-cheng added a comment. Discussion on riscv-v-spec : https://github.com/riscv/riscv-v-spec/issues/723#issuecomment-922153867, although v-spec and isa-spec still not clearly describe that, but seems ISA folks prefer having those implication relationship between those zve* and v extensions.
