Allow any declaration to be marked with `@unsafe`, meaning that it
involves unsafe code. This also extends to C declarations marked with
the `swift_attr("unsafe")` attribute.
Under a separate experimental flag (`DisallowUnsafe`), diagnose any
attempt to use an `@unsafe` declaration or any unsafe language feature
(such as `unowned(unsafe)`, `@unchecked Sendable`). This begins to
define a "safe" mode in Swift that prohibits memory-unsafe constructs.
