Move from build-tools to weaver

[trisch-me]

Hey everyone, semconv is going to deprecate build-tools and actively moving to use weaver. As a part of this effort we are going to update all codegen for different languages including golang.

I will work on updating https://github.com/open-telemetry/opentelemetry-go-build-tools/tree/main/semconvgen and testing it with new weaver docker image.

If you have any questions please let me know

@dmathieu FYI

We should actually replace semconvgen with weaver.

@trisch-me do you happen to have an update on the progress on the work updating https://github.com/open-telemetry/opentelemetry-go-build-tools/tree/main/semconvgen.

Can you share plans or outstanding tasks that would bring this issue forward? Is there a way to help?

@MrAlias or is the plan to dropsemconvgen and migrate the sem conv code generation to weaver?

[trisch-me]

@florianl I think the best way is to ask @MrAlias about current process as he owns the process now and does migration.

@florianl please see #5898
