slog: add context arguments

Implement a more direct way to pass a context to a Handler.

- Add {Info,Debug,Warn,Error}Ctx functions and methods, that take a context.

- Add an initial context argument to Log and LogAttrs.

- Remove Logger.WithContext, Logger.Context and the Record.Context
  field: the output functions will pass their context argument
  directly to the Handler.

This CL also includes a somewhat unrelated set of changes:

- Add the Record.Add(...any) method, which behaves like Record.AddAttrs
  but processes its arguments like Logger.Log.

- Remove LogDepth and LogAttrsDepth, since they can now be implemented
  with exported API.

A later CL will update the package documentation.
