Cast a mutable slice of possibly initialized bytes into a slice of initialized bytes, assuming it is initialized.

Safety

For this to be safe, the initialization invariant must be upheld, exactly like when reading.

NOTE: This must not be used for initializing the buffer. If unsafe code is still somehow, always initialize this by copying from another MaybeUninit slice, or using std::ptr::copy or std::ptr::copy_nonoverlapping.
