Alex Crichton 4b4dc0a479 Fix a bug in Cargo's cyclic dep graph detection
Cargo's cyclic dependency graph detection turns out to have had a bug
for quite a long time as surfaced by #9073. The bug in Cargo has to do
with how dev-dependencies are handled. Cycles are "allowed" through
dev-dependencies because the dev-dependency can depend on the original
crate. Our cyclic graph detection, however, was too eagerly flagging a
package as known to not have a cycle before we had processed everything
about it.

The fix here was basically to just simplify the graph traversal. Instead
of traversing the raw `Resolve` this instead creates an alternate
in-memory graph which has the actual edges we care about for cycle
detection (e.g. every edge that wasn't induced via a dev-dependency).
With this simplified graph we then apply the exact same algorithm, but
this time it should be less buggy because we're not trying to do funky
things about switching sets about what's visited halfway through a
traversal.

Closes #9073
