Oleksandr "Alex" Zinenko 2798b72ae7 [mlir] introduce debug transform dialect extension (#77595)
Introduce a new extension for simple print-debugging of the transform
dialect scripts. The initial version of this extension consists of two
ops that are printing the payload objects associated with transform
dialect values. Similar ops were already available in the test extenion
and several downstream projects, and were extensively used for testing.
