[8.18] [Gradle] Remove unused spool support in LoggedExec (#133767) (#134655)

* [Gradle] Remove unused spool support in LoggedExec (#133767)

This is not used anywhere so we should simplify this down to what
we actually use.

Fixes #119509

(cherry picked from commit 8c6162e)

# Conflicts:
#	muted-tests.yml

* Fix merge conflict
