Michał Jadwiszczak 233f4dcee3 db/view/view_building_worker: register staging sstable to view building coordinator when needed ...

Change return type of `check_needs_view_update_path()`. Instead of
retrning bool which tells whether to use staging directory (and register
to `view_update_generator`) or use normal directory.

Now the function returns enum with possible values:
- `normal_directory` - use normal directory for the sstable
- `staging_directly_to_generator` - use staging directory and register
      to `view_update_generator`
- `staging_managed_by_vbc` - use staging directory but don't register it
      to `view_update_generator` but create view building tasks for
      later

The third option is new, it's used when the table has any view which is
in building process currrently. In this case, registering it to `view_update_generator`
prematurely may lead to base-view inconsistency
(for example when a replica is in a pending state).
