[Apizr] Generate Apizr formatted Refit interface without .refitter settings file

[JeremyBP]

That was the missing part of the #404 puzzle.
Previous #428 PR focused on generating things from a .refitter settings file.

Now with that PR we can generate Apizr formatted Refit interfaces without settings file but with such a command line:

refitter https://petstore3.swagger.io/api/v3/openapi.yaml --use-apizr

It will generate the Refit interface, but formatted to Apizr by:

• Adding a final IApizrRequestOptions options parameter to all generated methods
• Providing cancellation tokens by Apizr request options instead of a dedicated parameter
• Using method overloads instead of optional parameters

So now we should get best of both CLI & SourceGenerator worlds 🥂
