[PATCH 0/8] pin-init sync for v6.16

[Benno Lossin <benno.lossin@proton.me>]

Synchronize changes from the upstream repository for v6.16. Branch with
all commits on top can be found at [1].

I did not expect that I would synchronize a lot of changes this soon,
but here we are. They are pretty conservative, so I don't expect anyone
to object (if you do find something, of course speak up!). A short
overview of the changes:

* Make the `Zeroable` derive macro compatible with field visibility and
  add union support.
* Add a new derive macro for `Zeroable` in order to allow deriving it in
  bindgen-generated crates.
* Add the `Wrapper` trait to allow initializing wrapper types (such as
  `UnsafeCell` and `UnsafePinned`) via pin-initializers.
