rust: pin-init: internal: add missing where clause to projection types
`#[pin_data]` failed to propagate the struct's `where` clause to the
generated projection struct. As a result, bounds written in a `where`
clause could be dropped during expansion, causing type errors when
fields depended on those bounds.
Fix this by adding the missing `where` clause to the generated
projection struct.
