rust: init: add initialization macros
Add the following initializer macros:
- `#[pin_data]` to annotate structurally pinned fields of structs,
needed for `pin_init!` and `try_pin_init!` to select the correct
initializer of fields.
- `pin_init!` create a pin-initializer for a struct with the
`Infallible` error type.
- `try_pin_init!` create a pin-initializer for a struct with a custom
error type (`kernel::error::Error` is the default).
- `init!` create an in-place-initializer for a struct with the
`Infallible` error type.
- `try_init!` create an in-place-initializer for a struct with a custom
error type (`kernel::error::Error` is the default).
Also add their needed internal helper traits and structs.
