1daf3408 - [RISCV] Set RVVConstraint = NoConstraint in tablegen classes with vm=1. NFC (#181960)

[RISCV] Set RVVConstraint = NoConstraint in tablegen classes with vm=1. NFC (#181960) Our RVV base classes default to RVVConstraint = VMConstraint. We should force it to NoConstraint in classes where we've explicitly marked vm as being a constant rather than an operand. This avoids needing to do it at a higher level in the class hierarchy.
