feat: support stampinf version override

[krishnakumar4a4]

This pull request introduces improved handling of the STAMPINF_VERSION environment variable for the driver packaging process, ensuring that the stampinf tool correctly sets the DriverVer field when the environment variable is present. It also adds a robust utility for managing environment variables in tests, and updates existing tests to use this utility to ensure isolation and reliability. Additionally, a new test is added to verify the STAMPINF_VERSION override logic. The changes also add the regex crate as a workspace dependency.

Environment variable handling and testing improvements:

• Added a new with_env utility function for safely setting and restoring environment variables in tests, ensuring test isolation and preventing cross-test contamination. This function is now used throughout all relevant tests. (crates/cargo-wdk/src/main.rs, crates/cargo-wdk/src/actions/build/tests.rs) [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18]

STAMPINF_VERSION environment variable support:

• Updated the run_stampinf logic so that if the STAMPINF_VERSION environment variable is set and non-empty, the -v argument is omitted, allowing stampinf to read and use the environment variable for the DriverVer field. Otherwise, the default -v * argument is used. (crates/cargo-wdk/src/actions/build/package_task.rs) [1] [2]
• Added a dedicated test to verify that the presence, absence, or emptiness of STAMPINF_VERSION correctly influences the arguments passed to stampinf. (crates/cargo-wdk/src/actions/build/package_task.rs)

Dependency management:

• Added the regex crate as a workspace dependency in Cargo.toml for future or current use. (crates/cargo-wdk/Cargo.toml)

Integration test updates:

• Updated integration tests to use the new with_env utility and to define STAMPINF_VERSION_ENV_VAR for consistency. (crates/cargo-wdk/tests/build_command_test.rs)

These changes collectively improve the reliability of the build process when environment variables are involved, and make the test suite more robust and maintainable.

Pull Request Overview

This pull request introduces conditional support for overriding the DriverVer version in the stampinf tool through an environment variable when unstable build flags are enabled.

• Adds conditional logic to allow STAMPINF_VERSION environment variable to override auto-generated driver version
• Implements parameterized testing to verify the new conditional behavior
• Updates configuration to support linting and documentation of the new unstable cfg flag
