[APM] Prevent imports of server in public code

[cauemarcondes]

Following this fix #67210, now we need to remove all server imports from the public code.

All files that import from apm/server in the public folder, such as:

https://github.com/elastic/kibana/blob/master/x-pack/plugins/apm/public/components/app/ErrorGroupOverview/List/index.tsx#L14-L15

An easy way to track it is find all files that disabled @kbn/eslint/no-restricted-paths rule.

What's missing?

In the public directory, we have a lot of direct imports from apm/server which the error are disabled by // eslint-disable-next-line @kbn/eslint/no-restricted-paths

Okay, can you update the description with an example - so it's clear what's missing.

Looks like it's mostly types being imported in the client from the server. I'm wondering if we can use type-only imports to signal to eslint that this is not a problem.

If not, I don't think we should make larger refactorings to accommodate an eslint rule. It's perfectly fine to import types across server/client boundaries.
