[NewPM][CodeGen] Add `MachineFunctionAnalysis` (#88610)

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`.
