[Findit] Flake Analyzer - Save build and try job urls to data points

This change removes the dependency of Flake Analyzer's saving data points
needing any build-level information. Instead of getting it when creating
data points, it is retrieved when the isolate sha is generated and propagated
down to updating data points.
