dev: Start using `#[expect]` instead of `#[allow]` (#9696)

* Start using `#[expect]` instead of `#[allow]`

In Rust 1.81, our new MSRV, a new feature was added to Rust to use
`#[expect]` to control lint levels. This new lint annotation will
silence a lint but will itself cause a lint if it doesn't actually
silence anything. This is quite useful to ensure that annotations don't
get stale over time.

Another feature is the ability to use a `reason` directive on the
attribute with a string explaining why the attribute is there. This
string is then rendered in compiler messages if a warning or error
happens.

This commit migrates applies a few changes across the workspace:

* Some `#[allow]` are changed to `#[expect]` with a `reason`.
* Some `#[allow]` have a `reason` added if the lint conditionally fires
  (mostly related to macros).
* Some `#[allow]` are removed since the lint doesn't actually fire.
* The workspace configures `clippy::allow_attributes_without_reason = 'warn'`
  as a "ratchet" to prevent future regressions.
* Many crates are annotated to allow `allow_attributes_without_reason`
  during this transitionary period.

The end-state is that all crates should use
`#[expect(..., reason = "...")]` for any lint that unconditionally fires
but is expected. The `#[allow(..., reason = "...")]` lint should be used
for conditionally firing lints, primarily in macro-related code.
The `allow_attributes_without_reason = 'warn'` level is intended to be
permanent but the transitionary
`#[expect(clippy::allow_attributes_without_reason)]` crate annotations
to go away over time.

* Fix adapter build

prtest:full

* Fix one-core build of icache coherence

* Use `allow` for missing_docs

Work around rust-lang/rust#130021 which was fixed in Rust 1.83 and isn't
fixed for our MSRV at this time.

* More MSRV compat
