Multiple Entry Points For Entry Point Driver

[ScottCarda-MS]

Refactors the Entry Point Driver and C# generation to accommodate Q# code having multiple entry points.

Major Changes:

• Updated C# generation:
  • Now generate a unique entry point class for each entry point. These classes will no longer contain a Main method.
  • The Main method is generated in its own namespace and class: __QsEntryPoint__.__QsEntryPoint__.
  • Added a public function generateMainSource to the C# gen's EntryPoint module. This function parallels generateSource in the same module and generates the content for the C# gen's Main file.
  • The outputted files for C# gen are now:
    • the .g.cs for the C# of the Q# operations (same as before)
    • .g.EntryPoint.cs instead of EntryPoint.g.cs for generated entry point classes
    • EntryPoint.g.Main.cs for the name of the new file containing the Main method.
• Microsoft.Quantum.EntryPointDriver.Azure.Submit was made public as it is used in the generated C# for entry points.
• Microsoft.Quantum.EntryPointDriver.Simulation.Simulate was made public as it is used in the generated C# for entry points.
• The IEntryPoint interface was changed considerably.
• And more changes under the Entry Point Driver project. Too many to list here 😄.
