Rollup merge of rust-lang#107736 - tgross35:atomic-as-ptr, r=m-ou-se

 Rename atomic 'as_mut_ptr' to 'as_ptr' to match Cell (ref rust-lang#66893)

Originally discussed in rust-lang#66893 (comment)

~~This uses rust-lang#107706 as a base to avoid a merge conflict once that gets rolled up (so disregard const changes in the diff until it does)~~ all merged & rebased
