4d2af858 - [LifetimeSafety] Track dereference operators behind a flag (#176794)

[LifetimeSafety] Track dereference operators behind a flag (#176794) Add a parameter to `shouldTrackImplicitObjectArg` to differentiate between lifetime safety analysis and statement-local analysis. The statement-local analysis was experiencing false positives when tracking dereference operators for GSL pointers, so this change allows for more aggressive tracking in the full analysis while being more conservative in the statement-local analysis. - Added a `RunningUnderLifetimeSafety` boolean parameter to `shouldTrackImplicitObjectArg` function to distinguish between lifetime safety analysis and Sema's statement-local analysis - Enhanced tracking of dereference operators for GSL pointers in STL: - Now tracks both `operator*` and `operator->` when running under lifetime safety analysis - Avoids tracking these operators in statement-local analysis to prevent false positives
