Explicitly list generator dependencies

Updates dawn_json_generator and a template it depends on to properly
declare and handle dependencies on various JSON files used for
generation.

Previously, we solely relied on an underlying usage of a depfile
argument to surface these dependencies, which worked on the older GN
recipe that did not use `gn analyze` on trybots. However, since the
gn_v2 recipe automatically uses `gn analyze` to avoid unnecessary
compilations and depfile appears to be only usable at build time
(whereas `gn analyze` uses static analysis), not explicitly declaring
the dependency on the JSON files allows regressions caused by those
files to make it past the CQ.

Ignore stderr when retrieving remote revision

Keeps stdout and stderr separate in roll_chromium_deps.py when getting a
remote HEAD revision. This is a speculative fix for the autoroller
getting clearly incorrect (timestamp-like) revisions that are not seen
when running locally. ANGLE's equivalent keeps stdout and stderr
separate.

Expectations for Windows code coverage bots

No clue why these are specific to these bots. Adding the unexplained
timeouts with [ Slow ] to start, if that doesn't work, I'll upgrade to
[ Failure ] / [ RetryOnFailure ] (see patchset 1).

(No-Try because just adding expectations that will be checked by
presubmit.)
