[sync] Componentize sync: Part 2: Add SYNC_EXPORTs to files in src/sync/

One of the long term goals of the sync team is to pull sync code out of
chrome.dll and into its own component. As of today, several chrome targets
depend on various sync targets as defined in sync.gyp. We'd like to move
to a world where all chrome targets outside sync.gyp simply depend on the
target sync.gyp:sync, which is built into its own component.

This patch sets the stage for full componentization by adding
SYNC_EXPORT annotations to classes / methods within src/sync.

The final step of breaking off sync into its own component will be done
in https://codereview.chromium.org/11412211.
