Sync: Remove NonBlockingDataTypeManager and any ProfileSyncService code related to it.

Sync: Remove NonBlockingDataTypeManager and any ProfileSyncService code related to it.

This is cleanup of the code specific to NonBlockingDataTypeManager
that shouldn't be needed anymore with the new implementation
based on DataTypeManager shared between the regular datatypes
and USS datatypes.

Please note that there currently no unit tests for
NonBlockingDataTypeManager and no tests for the methods
removed from ProfileSyncService. There are unit tests for
NonBlockingDataTypeController that use the class directly
without the manager.

NonBlockingDataTypeController remains unchanged for now.
I'll change it in a separate change.
