Improve Integration Test by Generating TLS/mTLS Certificates via MSBuild

[sandy2008]

Fixes #2009
Based on PR #4731

Changes

This PR introduces an improvement in how integration tests handle TLS/mTLS certificates by generating them at build time via MSBuild. The generated certificates are stored in the build output directory.

Key Changes:

• Added MSBuild tasks to generate certificates/keys during the build process.
• Certificates are generated via PowerShell on Windows and Bash on Unix.

Merge requirement checklist

• CONTRIBUTING guidelines followed (license requirements, nullable enabled, static analysis, etc.)
• Unit tests added/updated
• Appropriate CHANGELOG.md files updated for non-trivial changes
• Changes in public API reviewed (if applicable)
