Revert "[engsys] build test assets only for browser runs (Azure#27035)…

…" (Azure#27065)

This reverts commit e453c2d.

PR Azure#27035 keeps `build;test` only for browser runs. It turns out that a
couple of packages have custom `build:test` scripts that are different
from `build`. While we can explore more on enabling `build:test` for
these few packages, this PR reverts the changes to unblock automation
builds.
