This overload parses a pipeline string that contains the anchor operation type, and returns an OpPassManager corresponding to the provided pipeline. This is useful for various situations, such as dynamic pass pipelines which are not anchored within a parent pass pipeline. fixes #52813 Differential Revision: https://reviews.llvm.org/D116525
