Auto merge of #116233 - DaniPopes:stabilize-const_maybe_uninit_assume…

…_init_read, r=dtolnay Stabilize `const_maybe_uninit_assume_init_read` AFAICT the only reason this was not included in the `maybe_uninit_extra` stabilization was because `ptr::read` was unstable (#92768 (comment)), which has since been stabilized in 1.71. Needs a separate FCP from the [original `maybe_uninit_extra` one](#63567 (comment)). Tracking issue: #63567
