- Extend `@_inheritActorContext` attribute to support optional `always` modifier. The new modifier will make closure context isolated even if the parameter is not captured by the closure. - Implementation `@_inheritActorContext` attribute validation - it could only be used on parameter that have `@Sendable` or `sending` and `@isolated(any)` or `async` function type (downgraded to a warning until future major Swift mode to avoid source compatibility issues). - Add a new language feature that guards use of `@_inheritActorContext(always)` in swift interface files - Update `getLoweredLocalCaptures` to add an entry for isolation parameter implicitly captured by `@_inheritActorContext(always)` - Update serialization code to store `always` modifier (cherry picked from commit04d46760bb) (cherry picked from commitc050e8f75a) (cherry picked from commitc0aca5384b) (cherry picked from commita4f6d710cf) (cherry picked from commit6c911f5d42) (cherry picked from commit17b8f7ef12)
