[CodeGen][NewPM] Port `LiveIntervals` to new pass manager (#98118)
- Add `LiveIntervalsAnalysis`.
- Add `LiveIntervalsPrinterPass`.
- Use `LiveIntervalsWrapperPass` in legacy pass manager.
- Use `std::unique_ptr` instead of raw pointer for `LICalc`, so
destructor and default move constructor can handle it correctly.
This would be the last analysis required by `PHIElimination`.
