Rollup merge of #145467 - Kivooeo:stabilize-strict_provenance_atomic_ptr, r=scottmcm

Stabilize `strict_provenance_atomic_ptr` feature

This closes [tracking issue](https://github.com/rust-lang/rust/issues/99108) and stabilises `AtomicPtr::{fetch_ptr_add, fetch_ptr_sub, fetch_byte_add, fetch_byte_sub, fetch_or, fetch_and, fetch_xor}`
