Tracking issue for [T]::swap_with_slice feature

[scottmcm]

Exposes the simd-optimized ptr::swap_nonoverlapping in a safe API.

Pre-stabilization todo list:

• Bikeshed: should it maybe be swap_slice instead? (See discussion in Add [T]::swap_with_slice #44031)

Let’s get consensus to stabilize modulo naming:

@rfcbot fcp merge

In #44031 it seems like everyone is fine with both swap_with_slice and swap_slice, I tend to agree. Another option could be swap_slices, plural.

No concerns currently listed.

Once a majority of reviewers approve (and none object), this will enter its final comment period. If you spot a major issue that hasn't been raised at any point in this process, please speak up!

The current name of swap_with_slice seems reasonable to me.
