Revert of [Sync] Componentize ProfileSyncComponentsFactoryImpl (patchset #8 id:180001 of https://codereview.chromium.org/1421003007/ )

Reason for revert:
Fails unit tests on Android builds:
ProfileSyncServiceFactoryTest.CreatePSSDisableOne
ProfileSyncServiceFactoryTest.CreatePSSDisableMultiple
ProfileSyncServiceFactoryTest.CreatePSSDefault

Original issue's description:
> [Sync] Componentize ProfileSyncComponentsFactoryImpl
>
> Componentize ProfileSyncComponentsFactoryImpl into browser_sync component.
> As part of this, pull out RegisterDesktopDatatypes method into ChromeSyncClient.
> Similarly, a RegisterAndroidDataTypes is created instead for Android
> platforms.
>
> Because profile_sync_components_factory_impl_unittest.cc was really duplicating
> and testing the logic from ProfileSyncServiceFactory, went ahead and moved the
> test cases over into profile_sync_service_factory_unittest.cc.
