Rollup merge of #65046 - sinkuu:cell_reorder, r=shepmaster

Make `Cell::new` method come first in documentation

Methods to create a thing usually comes first in `std` documentation, and `Cell` has been an exception. Also, `T: Copy` specialized methods should not be on top of the page. (This had led me to miss that most of its methods are not bounded by `Copy`...)
