Currently, custom components do not respect `admin.condition` unless
manually wrapped with the `withCondition` HOC, like all default fields
currently do. This should not be a requirement of component authors.
Instead, we can automatically detect custom client and server fields and
wrap them with the underlying `WatchCondition` component which will
subscribe to the `passesCondition` property within client-side form
state.
For my future self: there are potentially multiple instances where
fields subscribe to conditions duplicately, such as when rendering a
default Payload field within a custom field component. This was always a
problem and it is non-breaking, but needs to be reevaluated and removed
in the future for performance. Only the default fields that Payload
renders client-side need to subscribe to field conditions in this way.
When importing a Payload field into your custom field component, for
example, it should not include the HOC, because custom components now
watch conditions themselves.
As field tests grow in size, they need to be moved out of the greater
fields test spec and into their own standalone files for readability,
maintainability, and speed. This way they we can write field tests in a
more isolated environment, and they can run in parallel in CI.
**BREAKING:**
- Type narrowing for `relationTo` props on filterOptions, relationship
fields and upload fields
- Type narrowing for arguments of lexical relationship, link and upload
features
