Remove Makefile

[cretz]

What was changed

To be consistent with other SDK repos, remove Makefile that was added in an unrelated PR at #561. May be reintroduced, but should at least get wider consensus and be called in CI to confirm it even works.

I find the Makefile helpful, and so I view it as an incremental step, potentially in a desirable direction, rather than as a violation of a previously existing policy. So that suggests discussion before removal.

I have not forgotten about this.

If we remove it, I would like to replace it with something platform-independent and standardized (as much as possible in the Go ecosystem anyway) that accomplishes the same goal. Otherwise I think having it (and maybe adding a script for Windows folks) is better than nothing.

This exists and is called go build and go run and was the accepted cross-platform method of working with the CLI until this Makefile got added in an unrelated PR sans discussion (compared to this PR which is getting discussion).

Dan and I have both explained why this is not the same thing as the Makefile--you might want to review that Slack discussion. If you need a pointer to it, poke me separately and I'll find it again for you.

👍 Definitely understood it's not the same thing as a Makefile, on purpose, it's better, consistent, more cross-platform, etc. There was a CLI way, this secretly changed, and looks like it's not going back.
