Page layout tab v2 (#16319)

# Introduction
Migrating `pageLayoutTab` to the v2 engine
- Types and constants
- Builder and validate
- Runner

Introduced a new `StrictSyncableEntity` that enforces that
`universalIdentifier` and `applicationId` are defined
As these entities are brand new we could enforce this rule already
This still requires a migration command to associate the existing
entities to custom workspace application instance and define
universalIdentifier

Handled retro-comp of the migration through a migration as upgrade
command fallback
