This work is a continuation of [PR#140530](https://github.com/llvm/llvm-project/pull/140530), co-authored by @optimisan. The PR refactors `MachineModuleSlotTracker` to support both the Legacy Pass Manager and New Pass Manager by removing its direct dependency on `MachineModuleInfo`. `MachineModuleSlotTracker` requires `MachineModuleInfo` to obtain `MachineFunction` instances when printing MIR. But `MachineFunctionAnalysis` provides `MachineFunction` for NPM. This patch refactors `MachineModuleSlotTracker` to use a function callback (`MFGetterFnT`) instead of directly depending on `MachineModuleInfo`. --------- Co-authored-by: vikhegde <vikram.hegde@amd.com>
