[Mlir-commits] [mlir] [mlir] introduce transform.num_associations (PR #76723)

Is it worth adding a verifier that the result type is either `param<i64>` or `any_param`? Right now this lets users write
```mlir
%p = transform.num_associations %op : (!transform.any_op) -> !transform.param<i32>
```
which will fail during application.
