Validate all rustdoc builds

[AdamGS]

Summary

Make sure to actually build rustdoc for all features and crates in the workspace, including private docs.

This PR also includes fixes for every failure I've found. In some cases we had references to dead types/interfaces, I've tried to keep the intent as close as possible to original intent.

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.
