feat!: fix non-functional custom RSC component handling, separate label and description props, fix non-functional label function handling (#6264)

Breaking Changes:

- Globals config: `admin.description` no longer accepts a custom component. You will have to move it to `admin.components.elements.Description`
- Collections config: `admin.description` no longer accepts a custom component. You will have to move it to `admin.components.edit.Description`
- All Fields: `field.admin.description` no longer accepts a custom component. You will have to move it to `field.admin.components.Description`
- Collapsible Field: `field.label` no longer accepts a custom component. You will have to move it to `field.admin.components.RowLabel`
- Array Field: `field.admin.components.RowLabel` no longer accepts strings or records
- If you are using our exported field components in your own app, their `labelProps` property has been stripped down and no longer contains the `label` and `required` prop. Those can now only be configured at the top-level
