[RISCV] When VLEN is exactly known, prefer VLMAX encoding for vsetvli (#75412)
If we know the exact VLEN, then we can tell if the AVL for particular
operation is equivalent to the vsetvli xN, zero, <vtype> encoding. Using
this encoding is better than having to materialize an immediate in a
register, but worse than being able to use the vsetivli zero, imm,
<type> encoding.
