feat: add startup and performance benchmarks

[TimothyMakkison]

• Used file scoped namespaces and simplified Program.cs
• Added PerformanceBenchmark to measure the speed to create and make the average request.
• StartupBenchmark measures Refit api creation and call time.
  • Measures: Service creation time, service creation and first call, just first call.
  • Not sure if its worth having the first call benchmarks as they have contradictory results. Why does FirstCallComplexRequestAsync use less memory than repeated calls? I might be missing something.
