cq_deps: Process deps of unsubmitted parents
Process dependencies of unsubmitted parent CLs. If CL A has parent B and
B is unsubmitted and depends on C in another repository, cq_deps will
list C as a dependency of A.
There are a couple corner cases. If A depends an B and B depends on C
which is an unsubmitted parent of A, then C is not listed as a
dependency of A—that dependency is already implicit when patching in A.
Another corner case is that in the same case as above (A depends on B
depends on C which is an unsubmitted parent of A) except A is based on
an out-of-date version of C. In this case tryjobs for B and C will
check out code successfully but tryjobs for A will fail because it's not
based on a current version of its parent.
