Rollup merge of #90896 - jhpratt:stabilize_const_maybe_uninit, r=oli-obk
Stabilize some `MaybeUninit` behavior as const

This stabilizes the `MaybeUninit::as_ptr`, `MaybeUninit::assume_init`, and `MaybeUninit::assume_init_ref` as `const fn`. `MaybeUninit::as_mut_ptr` has been moved to a new flag: `const_maybe_uninit_as_mut_ptr`, which is blocked on #57349. `MaybeUninit::slice_assume_init_ref` can be `const fn` when the method is stabilized in general.

The relevant intrinsic has been stabilized as `const` as well, though this isn't user-visible. Due to the seemingly unrelated feature name I performed `rg const_assert_type` and found no other instances of it being used.
