[mlir][transforms] Add topological sort analysis

This change add a helper function for computing a topological sorting of a list of ops. E.g. this can be useful in transforms where a subset of ops should be cloned without dominance errors.

The analysis reuses the existing implementation in TopologicalSortUtils.cpp.
