Stabilize `atomic_as_ptr`

Fixes rust-lang#66893

This stabilizes the `as_ptr` methods for atomics. The stabilization feature gate used here is `atomic_as_ptr` which supersedes `atomic_mut_ptr` to match the change in rust-lang#107736.

This needs FCP.

New stable API:

```rust
impl AtomicBool {
    pub const fn as_ptr(&self) -> *mut bool;
}

impl AtomicI32 {
    pub const fn as_ptr(&self) -> *mut i32;
}

// Includes all other atomic types

impl<T> AtomicPtr<T> {
    pub const fn as_ptr(&self) -> *mut *mut T;
}
```

The `atomic_mut_ptr` feature was stabilized by
[rust-lang/rust#108419][1].

[1]: rust-lang/rust#108419

Pkgsrc changes:
 * Adjust patches and cargo checksums to new versions.
 * Adjust to not cross-build to 8.0, due to LLVM using c++17,
   so adjust USE_LANGUAGES.

Upstream changes:

Version 1.70.0 (2023-06-01)
==========================

Language
--------
- [Relax ordering rules for `asm!` operands]
  (rust-lang/rust#105798)
- [Properly allow macro expanded `format_args` invocations to uses
  captures] (rust-lang/rust#106505)
- [Lint ambiguous glob re-exports]
  (rust-lang/rust#107880)
- [Perform const and unsafe checking for expressions in `let _ =
  expr` position.]
  (rust-lang/rust#102256)

Compiler
--------
- [Extend -Cdebuginfo with new options and named aliases]
  (rust-lang/rust#109808)
  This provides a smaller version of debuginfo for cases that only
  need line number information (`-Cdebuginfo=line-tables-only`),
  which may eventually become the default for `-Cdebuginfo=1`.
- [Make `unused_allocation` lint against `Box::new` too]
  (rust-lang/rust#104363)
- [Detect uninhabited types early in const eval]
  (rust-lang/rust#109435)
- [Switch to LLD as default linker for {arm,thumb}v4t-none-eabi]
  (rust-lang/rust#109721)
- [Add tier 3 target `loongarch64-unknown-linux-gnu`]
  (rust-lang/rust#96971)
- [Add tier 3 target for `i586-pc-nto-qnx700` (QNX Neutrino RTOS,
  version 7.0)] (rust-lang/rust#109173),
- [Insert alignment checks for pointer dereferences as debug assertions]
  (rust-lang/rust#98112)
  This catches undefined behavior at runtime, and may cause existing
  code to fail.

  (rust-lang/rust#108283)
- [Add a builtin unstable `FnPtr` trait that is implemented for
  all function pointers]
  (rust-lang/rust#108080)
  This extends `Debug`, `Pointer`, `Hash`, `PartialEq`, `Eq`,
  `PartialOrd`, and `Ord` implementations for function pointers
  with all ABIs.
