[mlir][vector] Add vector.to_elements unrolling (#157142)
This PR adds support for unrolling `vector.to_element`'s source operand.
It transforms
```mlir
%0:8 = vector.to_elements %v : vector<2x2x2xf32>
```
to
```mlir
%v0 = vector.extract %v[0] : vector<2x2xf32> from vector<2x2x2xf32>
%v1 = vector.extract %v[1] : vector<2x2xf32> from vector<2x2x2xf32>
%0:4 = vector.to_elements %v0 : vector<2x2xf32>
%1:4 = vector.to_elements %v1 : vector<2x2xf32>
// %0:8 = %0:4 - %1:4
```
This pattern will be applied until there are only 1-D vectors left.
