target/riscv/kvm: get/set vector vregs[]
vregs[] have variable size that depends on the current vlenb set by the host, meaning we can't use our regular kvm_riscv_reg_id() to retrieve it. Create a generic kvm_encode_reg_size_id() helper to encode any given size in bytes into a given kvm reg id. kvm_riscv_vector_reg_id() will use it to encode vlenb into a given vreg ID. kvm_riscv_(get|set)_vector() can then get/set all 32 vregs.
