rust: pin-init: internal: pin_data: use HRTB to work around `trivial_bounds` for `Unpin`
`#[pin_data]` generates a `Unpin` implementation for the user, which
requires reasoning using field types. This is rejected by rustc as "trivial
bounds", which can only be specified using the
`#![feature(trivial_bounds)]`.
Currently we use an extra lifetime in `__Unpin` to work around this; use
HRTB to introduce a dummy lifetime can achieve the same, which the
`Zeroable` implementation already uses.
Unify the `Unpin` impl to also use the same HRTB trick that `Zeroable`
uses. This produces slightly better error message and slightly shorter
expansion.
