The cpu-prof tests hand-rolled a partial version of what test/common/child_process already provides: log the child's stderr when the status is non-zero, then assert the status. That manual version never shows stdout, the signal, or the command that ran, so a CI failure gives less information than the helper would. Replace those blocks with spawnSyncAndExitWithoutError(). Every existing expectation is preserved -- status 0 is still required, and signal null is now checked as well, matching the helper defaults. Only success-path blocks whose assertions map one-to-one onto the helper defaults are converted.

spawnSync()status checks in the eight--cpu-proftests withspawnSyncAndExitWithoutError()fromtest/common/child_process, following the same approach as #65552.These tests logged stderr when the status was non-zero and then asserted the status, so a CI failure never showed stdout, the signal, or the command that ran. The helper reports all of them. Status 0 is still required, and signal null is now checked as well, matching the helper defaults.
Only success-path blocks whose assertions map one-to-one onto the helper defaults are converted.
