Stepan Koltsov f539134e20 Do not allocate for ZST ThinBox attempt 2 (using const_allocate)

There's PR https://github.com/rust-lang/rust/pull/123184
which avoids allocation for ZST ThinBox.

That PR has an issue with unsoundness with misuse of `MaybeUninit`
(see comments in that PR).

This PR is much simpler implementation which does not have this
problem, but it uses `const_allocate` feature.
