Add functionality to clear session's collected metrics

Currently, when a user enables metrics reporting during a session,
the next UMA report will include metrics data from before metrics
reporting was enabled. This CL adds functionality to clear metrics
data (histogram data and stability metrics) to resolve this issue.
This CL only adds functionality to do so.

Rather, future CLs will call this functionality at places of interest,
e.g., when the user enables metrics reporting in the settings page
(chrome://settings/syncSetup).
