This creates a rotating build.trace.gz in the out directory that can be loaded with chrome://tracing. It'll include start and end timings for make/soong/kati/ninja, and it will import and time-correct the ninja log files. Test: m -j; load out/build.trace.gz in chrome://tracing Test: multiproduct_kati -keep; load out/multiproduct*/build.trace.gz Change-Id: Ic060fa9515eb88d95dbe16712479dae9dffcf626
