Reland "Enable 'Browsing data volume counters on Desktop' by default."

This reverts commit 93f190df6d1e0435e535a4336e1fe9035a5c9eb7.

The problem which caused the revert was the assumption that ProfileSyncService exists, which should be solved by the CL https://codereview.chromium.org/1413373012/ that landed in the meantime. The trybots did not catch it, as this issue was introduced after running git cl try on the original CL but before it landed.
