third-party/rust: patch rust-bindgen

Summary:
This includes 3 recent PRs:
- rust-lang/rust-bindgen#3305 - Fix packed structs with flexible array members (merged)
- rust-lang/rust-bindgen#3306 - Support nested flexible array members
- rust-lang/rust-bindgen#3307 - Add support for custom per-field attributes

The last one is specifically intended to allow per-field attributes from proc-macros to be applied.

These have been cherry-picked onto the v0.72.1 release branch, as the main branch is still listed as v0.72.0 and I didn't want a backwards version step. The upstream branch is https://github.com/jsgf/rust-bindgen/tree/PR-merged
