In new pass system, `MachineFunction` could be an analysis result again, machine module pass can now fetch them from analysis manager. `MachineModuleInfo` no longer owns them. Remove `FreeMachineFunctionPass`, replaced by `InvalidateAnalysisPass<MachineFunctionAnalysis>`. Now `FreeMachineFunction` is replaced by `InvalidateAnalysisPass<MachineFunctionAnalysis>`, the workaround in `MachineFunctionPassManager` is no longer needed, there is no difference between `unittests/MIR/PassBuilderCallbacksTest.cpp` and `unittests/IR/PassBuilderCallbacksTest.cpp`.
