Warn for duplicate ViewTransition names (#32752)

This adds early logging when two ViewTransitions with the same name are
mounted at the same time. Whether they're part of a View Transition or
not.

This lets us include the owner stack of each one. I do two logs so that
you can get the stack trace of each one of the duplicates.

It currently only logs once for each name which also avoids the scenario
when you have many hits for the same name in one commit. However, we
could also possibly log a stack for each of them but seems noisy.

Currently we don't log if a SwipeTransition is the first time the pair
gets mounted which could lead to a View Transition error before we've
warned. That could be a separate improvement.
