https://crrev.com/c/7234371 made some optimizations to the check
but caused it to start missing changes that modified DEPS but not
the corresponding gitlink.
Fix the check by doing a full tree scan when DEPS is updated.

Significantly reduces the execution time of presubmit checks by
optimizing CheckForCommitObjects.
For CLs with fewer than 1000 affected files, run `git ls-tree` only on
specific files instead of scanning the full tree. This yields a ~70x
speedup (~0.97s -> ~0.01s) for typical CLs.
