The `try_[pin_]init!` versions of the initializer macros are
superfluous. Instead of forcing the user to always write an error in
`try_[pin_]init!` and not allowing one in `[pin_]init!`, combine them
into `[pin_]init!` that defaults the error to
`core::convert::Infallible`, but also allows to specify a custom one.
Projects using pin-init still can provide their own defaulting
initializers using the `try_` prefix by using the `#[default_error]`
attribute added in a future patch.

The name `zeroed` is a much better fit for a function that returns the
type by-value.

The previous link anchor was broken in rust 1.77, because the
documentation was refactored in upstream rust.
Change the link to refer to the new section in the rust documentation.

The upstream version of the `README.md` differs by this change, so
synchronize it.
The reason that this wasn't in the original sync patch is that this was
a late change that I didn't port back to the kernel repo, since it was
generated by `cargo rdme`.
