feat(instrumentation): Add HTTP instrumentation

[kakkoyun]

Adds HTTP instrumentation.

Key changes

• a8992f6 adds the net/http client and server implementation. It mimics the upstream opentelemetry-go-contrib
• 6b4f804 Removes the existing abstractions around semantic conventions and instrumenter for a leaner approach with more flexibility.

I don't understand why typos check fails on that???! 😫

@kakkoyun Overall, LGTM and I like the direction.

Since many things have been simplified and several abstractions removed, the document
https://github.com/open-telemetry/opentelemetry-go-compile-instrumentation/blob/main/docs/api-design-and-project-structure.md

has become outdated. Do you plan to update it as part of this PR, or will that be done afterward?

I'll update it in this PR. Thanks for pointing it out.
