use xunit.v3 for unit tests

Update dependencies and refactor test framework

- Bump `Nerdbank.GitVersioning` to version `3.7.115`.
- Add new package references for `Tmds.ExecFunction`, `xunit.v3`, and `System.Buffers`.
- Remove outdated package references in `Directory.Packages.props`.
- Update `Microsoft.NET.Test.Sdk` and `xunit` versions across projects.
- Refactor tests to use standard `Fact` attributes instead of `ConditionalFact`.
- Enhance logging and error handling in `CoverletInProcDataCollector` and `InstrumentationTask` tests.
- Clean up deprecated code and comments in test files.
- Adjust project files for compatibility with the latest .NET SDK.
