Use the build start time from Soong main UI for metrics build timestamp.

Currently, the build timestamp saved to the build_date_timestamp
field in the MetricsBase metrics protobuf usually comes from a text
file named build_date.txt. It may not be accurate for metrics purposes.
Instead, use the build start time from Soong main UI for a better
timestamp.

Bug: b/140638454
Test: Ran and checked the build_date_timestamp by running the printproto
      command.
