DomUniverse: optimize counter handling in guaranteeUniverse()
Atomic counters are the prime examples for when relaxed atomic loads
suffice, so don't use the fully-ordered pre-increment operator, but
fetch_add(1, relaxed).
Add Q_CONSTINIT and wrap in a lambda as a drive-by.
The Q_CONSTINIT will be in dev only; it doesn't exist in 6.3.
Pick-to: 6.3 6.2
