Closes #3829
Alternative to #35417
I don't think the individual "WasOnDependencyCycle" attrs on units
are particularly helpful and comprehensible, as it's really about
the dep relationship between them. And as discussed, the dependency
cycle is not something persistent, rather local to the currently
loaded set of units and shall be reset with daemon-reload (see also
https://github.com/systemd/systemd/issues/35642#issuecomment-2591296586).
Hence, let's report system state as degraded and point users to
the involved transactions when ordering cycles are encountered instead.
Combined with log messages added in 6912eb315f
it should achieve the goal of making ordering cycles more observable,
while avoiding all sorts of subtle bookkeeping in the service manager.
The degraded state can be reset via the existing ResetFailed() manager-wide
method.
