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

68534a29d6 Don't print critical path parallelism ratio if elapsed time is 0.
Test: m nothing, examine out/soong.log

7b6245388c Compute critical path when ninja finishes
Keep a running map of the critical path to each edge as it
finishes.  At the end of the build, find the edge with the
longest critical path and print the path to out/soong.log.

Test: critical_path_test.go
