Revert "ci: revert EngFlow ios_build changes (#1700)" (#1704)

Description: This reverts commit c1ef46d4c62dd94a4a7a22c83e22fa6c99534be9.

The machine was running out of space because it was keeping large replicas of build artifacts for too long. We've since increased the disk space as well as decreased the timeout for evicting those large artifacts. Performance may be slightly degraded if those artifacts need to go to disk to be fetched but by looking at previous results it'll probably be ok

Risk Level: Low
Testing: See ios_build presubmit
Docs Changes: N/A
Release Notes: N/A
