feat(meshmultizoneservice): api

Checklist prior to review

MeshMultiZoneService api and validation.

xref #10507

Name is still under consideration, but I'd like to move forward with the rest of implem. We can still rename this before the next minor release.

The only divergence from the MADR is that instead of list of zones in status I have a list of matched mesh service. I think this will help XDS generation and can be useful in the GUI.

• Link to relevant issue as well as docs and UI issues --
• This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as a image registry) and it will work on Windows, system specific functions like syscall.Mkfifo have equivalent implementation on the other OS --
• Tests (Unit test, E2E tests, manual test on universal and k8s) --
  • Don't forget ci/ labels to run additional/fewer tests
• Do you need to update UPGRADE.md? --
• Does it need to be backported according to the backporting policy? (this GH action will add "backport" label based on these file globs, if you want to prevent it from adding the "backport" label use no-backport-autolabel label) --
