This pull request updates the Directory.Build.targets file to improve the build configuration for benchmark and test projects. The main changes add specific settings and dependencies for projects whose names contain "Benchmark" or "Tests", making it easier to manage benchmarks and tests consistently.

Benchmark project configuration:

• Added a property group to set OutputType to Exe, enable optimizations, disable packing, and exclude from SonarQube analysis for projects with "Benchmark" in their name.
• Added a BenchmarkDotNet package reference for benchmark projects.

Test project configuration:

• Added a property group to set OutputType to Exe and disable packing for test projects.
• Added a Using directive for Xunit in test projects.
• Updated the test content to include xunit.runner.json (instead of a linked testconfig.json) and copy it to the output directory.
• Added a Microsoft.TestPlatform.TestHost package reference for test projects.
