  [libc++][ranges] LWG3618: Unnecessary `iter_move` for `transform_view::iterator` (#91809)

## Introduction

This patch implements LWG3618: Unnecessary `iter_move` for
`transform_view::iterator`.

`transform_view`'s iterator currently specifies a customization point
for `iter_move`. This customization point does the same thing that the
default implementation would do, but its sole purpose is to ensure the
appropriate conditional `noexcept` specification.
