As part of the build team's effort to cleanup envseup.sh. Remove the run_tool_with_logging rundtion from envsetup.sh and add it as a standalone script under build/soong/bin Test: atest run_tool_with_logging Test: manually do source envsetup.sh and run adb devices -l and check the event log is sent to clearcut, tested with both bash and zsh Bug: 342066042 Change-Id: I2fbc69a064832af61d75d14b0e33a62cb56186df
