Remove surface_sync tests from all non-Android configs

Except on Android, surface sync (--enable-surface-synchronization) is on by
default. So keeping tests of it around are actually redundant.

This removes them from all configs except for 'viz_fyi_android_gtests' where we
want coverage to find bugs until we are ready to ship on Android.

TEST=surface_sync_browser_tests, surface_sync_content_browsertests
