Siem Readiness initial plugin and navigation, package, server api

[JordanSh]

Summary

Resolves #230516
Resolves #230533

This PR adds the initial infrastructure for the SIEM Readiness feature.

• Added as a new sub plugin within security solution with basic WIP UI
• Added simple Readme with enablement instructions
• Added (temporary) links to the feature page in both ESS and Serverless navigation menus. Will be updated to be part of the launchpad feature once its merged
• Added Advanced Settings feature flag
• Added experimental feature flag to hide the Advanced Setting from serverless users
• Added Kibana package that provides easy logging of tasks across security solution
• Added an API endpoint to handle index logging

How to enable

Create a local ESS environment (Advanced Setting flag is hidden in serverless regardless of kibana.dev.yml settings)

Enable the experimental flag in your kibana.dev.yml by adding this line:

xpack.securitySolution.enableExperimental: ['siemReadinessDashboard']

This should allow rendering of the Enable SIEM Readiness Dashboard setting in the Advanced Settings page via http://localhost:5601/app/management/kibana/settings. After switching on the toggle and reloading, the SIEM Readiness link should be available via the navigation menu and the search bar.

LGTM for the @elastic/security-threat-hunting-investigations team. Thank you for keeping this first PR very small and targeted, makes the review a lot nicer on everyone :)

Just one question regarding the management code owner review

[mattkime]

should this be imported from the management package?

[JordanSh]

let me know if i should move this, i've followed the pattern of other advanced settings from security solution as can be seen in this file

[mattkime]

I'm just curious why its defined in two different places. Its not a huge deal but I am trying to understand before delivering my approval.

[JordanSh]

thank you for noticing its being defined twice. indeed the other const in the management package ended up not being used at the end. i will remove it and only leave this one. thank you for catching this
