feat: add support for graphql-tools-executor

[YutaUra]

Which problem is this PR solving?

• Some GraphQL server libraries, such as graphql-yoga, use @graphql-tools/executor instead of graphql.js built-in executor.

Short description of the changes

• Instrument @graphql-tools/executor

I have used the existing graphql.js excutor implementation as a reference, but if there is anything missing or incomplete in the testing or source code, I would be glad to hear about it.

@YutaUra Sorry we have not had a chance to review this and it has been a while. Is this something you are still interested in, and would you be willing to be a maintainer of the instrumentation? This will be important to know before we can give this a thorough review. Thanks!

Facing the same problem, it makes sense to have this instrumented aswell. Since these instrumentations are rather low-level it took hours to figure out, why the instrumentation did not work as expected.

If it helps to understand why I ask, here is a link to some new guidance we've written about new instrumentations getting added to this repo.
