Rollup merge ofrust-lang#127071 - Sky9x:remove-ptr-to-from-bits, r=scottmcm
Remove (deprecated & unstable) {to,from}_bits pointer methodsThese unstable methods have been deprecated for more than a year (sincerust-lang#95583). Remove them.Seerust-lang#91126 (comment) andhttps://github.com/rust-lang/rust/pull/110441/files#r1169574509.Closesrust-lang#91126.r? `@scottmcm`
