  [LifetimeSafety] Gate lifetime checks behind per-diagnostic opts (#221610)

Granular Lifetime Safety Check Gating

We split `IsLifetimeSafetyEnabled` into individual check functions in
`SemaLifetimeSafety.h`.

These properties are stored in `LifetimeSafetyOpts`, which are then
checked inside the `Checker` to avoid invoking expensive reporting
functions mapping to diagnostics that are disabled.

`reportMisplacedLifetimebound` was found to be the most expensive
(possibly because it iterates on redecls).
