feat(ui): allows customizing version diff components, render versions ui on the server (#10815)

This PR moves the logic for rendering diff field components in the
version comparison view from the client to the server.

This allows us to expose more customization options to the server-side
Payload Config. For example, users can now pass their own diff
components for fields - even including RSCs.

This PR also cleans up the version view types

Implements the following from
https://github.com/payloadcms/payload/discussions/4197:
- allow for customization of diff components
- more control over versions screens in general

TODO:
- [x] Bring getFieldPaths fixes into core
- [x] Cleanup and test with scrutiny. Ensure all field types display
their diffs correctly
- [x] Review public API for overriding field types, add docs
- [x] Add e2e test for new public API
