ci: adopt Nuget and Arm64 changes from WDR

[krishnakumar4a4]

This pull request updates the CI workflow configuration files to improve platform and toolchain support, increase flexibility, and ensure compatibility with newer runners and tool versions. The changes mainly focus on refactoring matrix definitions, updating runner platforms, and refining environment variable usage across build, lint, formatting, and documentation workflows.

Platform and matrix configuration improvements:

• Refactored all workflow matrix definitions (build.yaml, lint.yaml, docs.yaml) to explicitly specify runner (windows-latest, windows-11-arm) and architecture (amd64, arm64), allowing jobs to run on both x64 and ARM Windows runners. [1] [2] [3]
• Updated target triples in matrix definitions to include both name and architecture, improving clarity and enabling more granular control over build and test targets. [1] [2]

Toolchain and environment variable updates:

• Changed WDK matrix entries to objects with version and source fields, and updated installation steps to use these fields, allowing selection between Winget and NuGet sources for different WDK versions. Also added logic to pass host and target architecture when using NuGet. [1] [2] [3]
• Updated Rust toolchain installation steps to use the new matrix structure, and changed Rust target specification to use the new target triple name field. [1] [2]

Runner platform standardization:

• Replaced windows-2025 with windows-latest for all jobs in formatting, lint, and audit workflows to ensure compatibility with currently supported GitHub-hosted runners. [1] [2] [3] [4]

Workflow logic enhancements:

• Added conditional logic to documentation and lint jobs to avoid duplicate runs on the same runner and architecture, improving CI efficiency.
• Enabled the fail-fast: false strategy in build, lint, and docs workflows to allow all matrix variants to complete even if some fail, improving visibility into failures across platforms. [1] [2] [3]
