Add a new OperationType handle type to the Transform dialect. This transform type is parameterized by the name of the payload operation it can point to. It is intended as a constraint on transformations that are only applicable to a specific kind of payload operations. If a transformation is applicable to a small set of operation classes, it can be wrapped into a transform op by using a disjunctive constraint, such as `Type<Or<[Transform_ConcreteOperation<"foo">.predicate, Transform_ConcreteOperation<"bar">.predicate]>>` for its operand without modifying this type. Broader sets of accepted operations should be modeled as specific types. Reviewed By: nicolasvasilache Differential Revision: https://reviews.llvm.org/D135586
