Jeongik Cha 28c1fe5bc8 Add critical path infomation into metrics
To improve build efficiency, the metrics for critical path and
parallelism ratio is necessary. That information has been included in
soong.log, so added it into metrics as well.

Bug: 271526845
Test: build and check if metrics pb has critical path info
