<!-- start_revert_body -->
This change reverts the following previous change:
These can be useful, but were probably left in past the point where they
are always useful:

- #58018
- #56342
- #74080

... compared to the cost of reading these logs with 1000s of lines of
`stdout: ` output.

Will ask the CI gods if any of this was load-bearing before sending out
for review.

…163017)

Re-lands #162644.

Reverts 7569fbf, with the change to
`ios_app_with_extensions_test.dart` omitted, which is intentional
(`--verbose` is load-bearing and used to check for a particular
message).
