[v6] Add Smoke Test + Fix parameter name

[joheredi]

• Add script for Smoke Testing supported sdks

  • Smoke test consists on Generating the sdk from a Readme.md and building without errors
  • Allow passing slice and size to smoke-test to be able to split smoke testing in chunks when the list of readmes grow.

• Fix for parameter names, we were using serializedNames instead of the name already processed by prenamer

Looks good! Keeping a list of specs to run like that is a good idea since you'll want to pull some from different branches on the specs repo (or forks). I probably should have done that for the benchmarking script.
