[shared-ux][packages] 1. Create Services Package

[clintandrewhall]

Summary

This is a subset of the work in #127419 for ease of review and commit history.

This PR refactors the Shared UX services to be stateless and free of dependency, and moves them from the shared_ux plugin to a package.

Why?

With only a few components, we've run into issues with circular dependencies. Our plugin is consuming code and types from other plugins, and once we do, those plugins can't use our plugin or its components. To mitigate this, we need to keep Shared UX as stateless and dependency free as possible.

Talking with ops, it became clear our assets don't actually need a plugin lifecycle to operate. This PR is one step in decoupling our components, services and utilities to packages.

TODO

• Complete .mdx documentation.
• File an issue to track TS unknown types, pending dependent teams moving their types to packages.
  • @elastic/kibana-app-services - DataView from src/plugins/data_views
