Adds cycle detection errors when top-level dynamic
configuration creation fails because transitive fragment
visitation hits these cycles.
This makes CircularDependencyTest pass with dynamic
configurations.
It's a little bit unfortunate that BuildViewTestCase
follows a different code path to create configured targets
than production (BuildView.getConfiguredTargetForTesting
vs. BuildView.update). As a result, doing an actual build over
the rules defined in CircularDependencyTest#testTwoCycles
correctly reports the cycle, while the test itself doesn't.
That means the test isn't 100% faithfully testing production
logic.
But I'm not interested in fixing the gap between
BuildView.update and BuildView.getConfiguredTargetForTesting
in this change. That's part of a larger refactoring effort
on the various forked ways of acccessing configured targets
and dependencies in BuildView.
