std: Export the select! macro

Mark it as #[experimental] for now. In theory this attribute will be read in the
future. I believe that the implementation is solid enough for general use,
although I would not be surprised if there were bugs in it still. I think that
it's at the point now where public usage of it will start to uncover hopefully
the last few remaining bugs.

Closes #12044
