From several dashboards, there are high spikes from several
builds where the real time of executing a part of the build
system took many many hours. This is due to using the wall
time clock when calculating the duration. For metrics, the
monotonic clock should be used for more accurate measurement.
Also, cleaned up the time.go file to use the proper proto
functions when marshalling perf protobuf and deleted
unnecessary functions.
Bug: b/143492984
Test: Wrote and ran unit test case.

The metrics.proto needs to be imported to Google3 in order to unmarshal
the build metrics data from bigstore. Cleaned up the enum names to use
the Camel naming convention and renamed the build_metrics to
soong_metrics to be more specific to soong and to allow quering
soong_metrics files from bigstore.
Bug: b/135280521
Test: lunch andf m -j. Checked if soong_metrics was generated correctly
by using printproto command.

Test: Dumped the text formated based metrics file to out dir,
and checked the file.
