Subject: [PATCH 1/2] Allow clippy::manual_div_ceil for generated bindings

bindgen 0.73 generates code that trips this lint, and CI treats
warnings as errors.

Subject: [PATCH 2/2] Bump bindgen from 0.72.0 to 0.73.2

bindgen 0.73 uses syn 3, which the locked prettyplease 0.2 (syn 2)
cannot accept, so bump prettyplease to 0.3.0 as well.

Fixes the CI failure of #3206.
