Remove non_exhaustive from enum definitions

[jhendrixMSFT]

Fixes #809

[Copilot]

Pull request overview

This PR removes the #[non_exhaustive] attribute from all generated Rust enum definitions to align with the design choice that enums should be exhaustive and fail at compile time when new variants are added. It also updates the enum code generator and records the change in the changelog.

Changes:

• Stopped emitting #[non_exhaustive] on all generated enums in the Rust code generator.
• Updated all test baselines (enums.rs files) to reflect enums without #[non_exhaustive].
• Documented the change under the unreleased 0.33.1 section of the changelog.
