[PATCH v2 01/28] rust: prelude: split re-exports into groups

[ojeda]

From: Miguel Ojeda <ojeda@xxxxxxxxxx>

Split the prelude re-exports into groups: first the ones coming
from the `core` crate, then `alloc`, then our own crates and
finally the ones from modules from `kernel` itself (i.e. `super`).

We are doing this manually for the moment, but ideally, long-term,
this could be automated via `rustfmt` with options such as
`group_imports` and `imports_granularity` (both currently unstable).
