Extends `vector.insert_strided_slice` and `vector.insert_strided_slice`
to allow scalable input and output vectors. For scalable sizes, the
corresponding slice size has to match the corresponding dimension in the
output/input vector (insert/extract, respectively).
This is supported:
```mlir
vector.extract_strided_slice %1 {
offsets = [0, 3, 0],
sizes = [1, 1, 4],
strides = [1, 1, 1] } : vector<1x4x[4]xi32> to vector<1x1x[4]xi32>
```
This is not supported:
```mlir
vector.extract_strided_slice %1 {
offsets = [0, 3, 0],
sizes = [1, 1, 2],
strides = [1, 1, 1] } : vector<1x4x[4]xi32> to vector<1x1x[2]xi32>
```
