Fixes https://github.com/payloadcms/payload/issues/10492
This PR fixes a few weird behaviours when `validate: true` is set on drafts:
- when autosave is on and you submit an invalid form it would get stuck in an infinite loop
- PreventLeave would not trigger for submitted but invalid forms leading to potential data loss
Changes:
- Adds e2e tests for the above scenarios
- Adds a new `isValid` flag on the `Form` context provider to signal globally if the form is in a valid or invalid state
- Components like Autosave will manage this internally since it manages its own submission flow as well
- Adds PreventLeave to Autosave too for when form is invalid meaning data hasn't been actually saved so we want to prevent the user accidentally losing data by reloading or closing the page
The following tests have been added

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
