[Security Solution] Extend the /upgrade/_perform API endpoint's contract migrating to Zod

[jpdjere]

Partially addresses (contract change only): #166376

Created in favour of: #189187 (closed)

Summary

• Extends contract as described in the POC, migrating from io-ts to Zod (search for Perform rule upgrade)
• Uses new types in endpoint, but functionality remains unchaged.

For maintainers

• This was checked for breaking API changes and was labeled appropriately

Since this is an internal endpoint, and we don't use MERGED yet, this should be safe. Defaulting to updating to TARGET anyways, until actual endpoint implementation is finished.

LGTM 👍 Thank you, @jpdjere, for migrating the legacy schemas to Zod, they look much nicer now!
