[Minimizer] for sequential mode, respect find_all setting (#134339)

Summary: Currently, for sequential mode, minimizer search terminates after a node is excluded via the user defined exclusion_fn. However, on some occasions we would like the search to continue past that for the remaining nodes. In this diff I am changing the termination criteria to respect the find_all setting, where we continue sequential search if it is set.

Test Plan: CI
