Disable precache on svelte.

Precache was enabled for svelte in http://crrev.com/c8e7c272, when the
experiment was only on dev, in the interest in seeing the maximum percent of
users that we could impact.

There is an unconfirmed possibility that the background service may slow down
phones with low RAM/CPU. Until we verify that it does not, we would like to
avoid launching on svelte devices, in order to eliminate any potential for
harm.

This change re-disables the service on svelte devices, by checking
PrivacyPreferencesManager#shouldPrerender() instead of
PrefServiceBridge#getNetworkPredictionEnabled().

Merge approved for M56 branch 2924 and M57 (likely branch is 2987 but please wait for the branch announcement email to come out before merging there).

As discussed please test on a Svelte device on Monday with an official build and let me know if anything goes awry, otherwise I'll assume we are all set.  Thanks!
