  [mlir][arith] `arith-to-apfloat`: Add vector support (#171024)

Add support for vectorized operations such as `arith.addf ... :
vector<4xf4E2M1FN>`. The computation is scalarized: scalar operands are
extracted with `vector.to_elements`, multiple scalar computations are
performed and the result is inserted back into a vector with
`vector.from_elements`.
