  [libc++] LWG3672: `common_iterator::operator->()` should return by value (#87899)

## Abstract

This pull request implements LWG3672: `common_iterator::operator->()`
should return by value. The current implementation specifies that this
function should return the underlying pointer by reference (`T*
const&`), but it would be more intuitive to return it by value (`T*`).
