Auto merge of #23894 - tbu-:pr_iter_length_position, r=pnkfelix

Added documentation of the panicking overflow to the `count` and `position`
methods of `IteratorExt`, also make them more obvious in the code.

Also mention that the `Iterator::next` method of the struct returned by
`IteratorExt::enumerate` can panic due to overflow.
Empowering everyone to build reliable and efficient software.
