Refactor navigation commands to use NAVIGATION engine key with payload (#19303)

- Adds a payload JSON column to `CommandMenuItem` and introduces a
unified `NAVIGATION` engine component key that replaces all individual
GO_TO_* keys
- Navigation commands now use the payload to determine their target
(either an objectMetadataItemId or a path), making navigation commands
dynamic and eliminating the need for a hardcoded engine key per object
- Includes a 1.21 upgrade command (refactor-navigation-commands) that
migrates existing GO_TO_* items to NAVIGATION items with the appropriate
payload, and applies a CHECK constraint enforcing payload coherence

TODO: In a second PR, create the sync between object metadata items and
the navigation command menu items
- Object metadata item created or enabled -> Create navigation command
- Object metadata item deleted or disabled -> Delete associated
navigation command

In another PR:
- Allow `label`, `shortLabel` and `icon` to resolve the
`navigateToObjectMetadataItem` dynamically in their interpolation
instead of being hardcoded in the command menu item
- Make the icon dynamic in the command menu items as the label so that
we can resolve ${navigateToObjectMetadataItem.icon} at runTime -> This
way we won't need to keep update the command menu item icon when we
update the objectMetadataItem icon
