vec::Splice can invalidate the slice::Iter inside vec::Drain.
So we replace them with dangling pointers which, unlike ones to
deallocated memory, are allowed.

Lift `T: Sized` bounds from some `strict_provenance` pointer methods

This PR removes requirement for `T` (pointee type) to be `Sized` to call `pointer::{addr, expose_addr, with_addr, map_addr}`. These functions don't use `T`'s size, so there is no reason for them to require this. Updated public API:

Don't do pointer arithmetic on pointers to deallocated memory

vec::Splice can invalidate the slice::Iter inside vec::Drain. So we replace them with dangling pointers which, unlike ones to deallocated memory, are allowed.

Fixes miri test failures.
