Description of Change

• After the migration to siso via #47534, on occasion on Windows mksnapshot or chromedriver fails to build which then causes errors while testing, eg https://github.com/electron/electron/actions/runs/18198927807/job/51842938994?pr=48439.

• It turns out there are several issues at hand here:

1. Build failures are silently failing/not marking the build as failing. This issue is addressed via electron/build-tools#759
2. The build failure seems to be happening because we run 2 targets back to back which seems to cause file contention on siso builds on Windows sometimes. In both cases instead of calling e build with the build target and then calling e build with the zip target, we can directly call e build with the zip target which should fix this contention issue.
3. chromedriver and mksnapshot are not used in our tests, so we are currently unnecessarily unzipping these zip files in our tests, so this PR removes unzipping those files.
