## Summary
Part of https://github.com/elastic/kibana/issues/201807
**Strategy**:
This PR assumes that `switchToModelVersionAt` has done it’s job and all
SO type owners now use `modelVersions` instead of `migrations`.
It takes the approach of trusting that this is fine™
**Changes in this PR:**
- `switchToModelVersionAt` removed from all registered saved objects, so
their mapping hash had to be updated.
- Implements `globalSwitchToModelVersionAt` directly in `version_map`
- Updates logic to prioritize `modelVersions` over `migrations` in
`getLatestMappingsModelVersion`, that previously relied on
`switchToModelVersionAt` being set
- Updates unit tests to match the refactored logic
- Updates snapshots
- Adapts SO types registered in the **cases**, **SLO** and **encrypted
saved objects** plugins.
- Updates docs
**Risks**:
- Plugin developers disregard the deprecated status of `migrations` and
introduce new versions, which will not be BWC. Saved object type hash
changes will notify the core team for a code owner review. The core team
needs to investigate the related changes and provide feedback.
