edgedb-go Add edgeql to go code generator

This change implements the default behavior outlined in https://github.com/edgedb/edgedb/discussions/4244. All arguments and options to the generator command are left for future work along with query hashing.

The documentation, help text, and cmd/edgeql-go/testdata directory may be areas of interest for reviewers.

This is related to https://github.com/edgedb/edgedb-go/issues/182

Is edgeql-go an appropriate name for the go codegen binary?

@divan and anyone else that would like, we would love to have early feedback from the community on this feature if you are interested in trying it out.

Currently all generated query functions are public. I think they should be private by default. Then if people ask for it we can provide a mechanism to tell the generator to make query functions public on a per query basis.
