[PATCH 1/1] rust: prelude: improve generated docs for `build_assert`

[melihemik]

The build assertion macros are documented in the `build_assert` module,
where rustdoc can show their purpose, where each macro should be used and
how a failed assertion is reported during compilation.

After the macro definitions were hidden to avoid duplicate root-level
documentation, however, rustdoc stopped rendering the explicit
`build_assert::{...}` re-exports on the prelude page. Readers of the
generated prelude documentation can no longer tell that `build_assert!`
and the related macros are brought into scope by `kernel::prelude::*`.

Use a glob re-export from the canonical module so rustdoc renders the
prelude entry as a re-export without inlining another copy of the macro
documentation.
