Pull Request Overview

This PR enhances D binary and test rules with runtime data and environment variable support, along with several improvements to the codebase structure and tooling. The primary purpose is to add 'env' and 'data' attributes to d_binary and d_test rules, allowing for better runtime configuration and data dependencies.

• Added env and data attributes to both d_binary and d_test rules with location and make variable expansion
• Fixed a typo in the resolved_toolchain definition from dinfo to d_toolchain_info
• Improved the curl downloader implementation with better error handling and timeout configurations

[nitpick] The 600-second (10 minutes) timeout may be excessive for most use cases. Consider using a more reasonable default timeout (e.g., 120 seconds) or making it configurable.
