**Description**: This adds "task name" parameter to all task creating functions. This is done in a few ways, e.g. we can backdeploy this to 5.1 in APIs which do not accept the `TaskExecutor` but it they do we provide a version for 6.0+ etc. This was requested in the SE acceptable of this proposal [Acceptance post SE-0469](https://forums.swift.org/t/accepted-with-modifications-se-0469-task-naming/79438). This moves all these declarations to gyb since going through them one by one has become unmaintainable otherwise. **Scope/Impact**: All task creation APIs now gain a new task name parameter. **Risk:** Medium, changes existing APIs rather than adding "even more overloads" though this risk was discussed in the team and accepted. This has a potential to be source breaking it someone used Task.init and friends as function. **Testing**: CI testing, source compatibility suite testing **Reviewed by**: **Original PR:** - https://github.com/swiftlang/swift/pull/81107 build changes required for this - https://github.com/swiftlang/swift/pull/80984 **Radar:** --------- Co-authored-by: Kuba Mracek <mracek@apple.com>
