Complement to #3967 , adds a `(since := "<date>")` field to `@[deprecated]` so that metaprogramming code has access to the deprecation date for e.g. bulk removals. Also adds `@[deprecated "deprecation message"]` to optionally replace the default text "`{declName}` has been deprecated, use `{newName}` instead".
