It has 3 options for now.
* ninja_log: uses ninja log file for data source
* evenly_distributed: pass empty list for ninja to consider every work as the same
* not_used: do not use critical path logic in ninja

In addition, I added the option in the metrics to track

Bazel boolean attributes can only support true or false states, but the
clang-tidy logic changes for modules which don't set a specific value.
Therefore, the tidy attribute should really be a tri-state of "true",
"false", or "" (unset).

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.
