std: Enable atomic.fence emission on wasm32 This commit removes the `#[cfg]` guards in `atomic::fence` on wasm targets. Since these guards were originally added the upstream wasm specification for threads gained an `atomic.fence` instruction, so LLVM no longer panics on these intrinsics. Although there aren't a ton of tests in-repo for this right now I've tested locally and all of these fences generate `atomic.fence` instructions in wasm. Closes #65687 Closes #72997

Only mention `u8` and not booleans

Improve the new documentation to be more precise about the necessary platform's capabilities

Add a Note: comment in documentation when the type/method/function is not always available

Stabilize AtomicN::fetch_min and AtomicN::fetch_max Some architectures (ARMv8.1 LSE and RISC-V) have specific instructions for atomic min/max which the compiler can only generate through explicit instrinsics.
