Fully qualify more types in source generated code to avoid namespace clashes (#2797)

* Globally qualify more types in source generated code

* Fix unqualified type references in source generator

Ensure all generated code uses globally qualified type names to prevent compilation errors when types are not in scope or have naming conflicts.

Changes:
- Fixed unqualified generic types in method signatures (IAsyncEnumerable, Func, Task)
- Added global:: prefix to System.Collections.IEnumerable references
- Qualified all exception types (InvalidOperationException, ArgumentException, NotSupportedException)
- Qualified System.Diagnostics.Debug.WriteLine calls
- Fixed CancellationToken, CancellationTokenSource, and TimeSpan references
- Qualified all System.Reflection.BindingFlags usages

This resolves compilation errors in projects using TUnit where generated code references types like Func<>, IAsyncEnumerable<>, and Task<> without proper qualification.
