feat: enhance cargo metadata parsing to respect config.toml

[wmmc88]

This pull request improves how the build system and the wdk-build crate handle Cargo workspace configuration, particularly with respect to custom config.toml files and patched dependencies. It also adds a new test workspace to verify these behaviors and updates the CI workflows to build and test this new setup.

Build system and metadata resolution improvements:

• Updated wdk-build to always run cargo_metadata from the top-level Cargo workspace directory, ensuring that custom .cargo/config.toml (including [patch] tables) are respected for dependency resolution. This includes adding debug-level tracing and more robust path handling in bindgen.rs and lib.rs. [1] [2] [3] [4] [5]

Continuous Integration (CI) enhancements:

• Modified the GitHub Actions workflows to build and package the new test workspace and to run its tests using cargo make, ensuring the new configuration is tested in CI. [1] [2]

Testing for custom config.toml and patched dependencies:

• Added a new test workspace customized-config-toml-workspace under tests/, which demonstrates and verifies that [patch.crates-io] entries in .cargo/config.toml are honored during build and metadata resolution. This includes a patched dependency, a test crate, and a build script that exercises the new logic. [1] [2] [3] [4] [5] [6] [7] [8]Improve handling of cargo metadata to respect config.toml configurations and add build and package steps for tests in GitHub workflows. Introduce a new library crate and a workspace to facilitate these changes.
