In some cases this pattern may ignore static information due to dynamic
operands in the insert_slice sizes operands, e.g.:
```
%0 = tensor.cast %arg0 : tensor<1x?xf32> to tensor<?x?xf32>
%1 = tensor.insert_slice %0 into %arg1[...] [%s0, %s1] [...]
: tensor<?x?xf32> into tensor<?x?xf32>
```
Can be rewritten into:
```
%1 = tensor.insert_slice %arg0 into %arg1[...] [1, %s1] [...]
: tensor<1x?xf32> into tensor<?x?xf32>
```
This PR updates the matching in the pattern to allow rewrites like this.
