Rollup merge of #88353 - jhpratt:stabilize-array-as-ref, r=joshtriplett

Partially stabilize `array_methods`

This stabilizes `<[T; N]>::as_slice` and `<[T; N]>::as_mut_slice`, which is forms part of the `array_methods` feature: #76118.

This also makes `<[T; N]>::as_slice` const due to its trivial nature.
