What this PR does / why we need it:

StreamFeatureView.__copy__ doesn't pass offline, enable_tiling, tiling_hop_size or stream_engine to the constructor, so the copy falls back to the defaults. Since with_name, with_projection and __getitem__ all go through __copy__, a projected stream view silently loses tiling and its engine config. FeatureView.__copy__ already passes offline.

sfv = StreamFeatureView(..., offline=True, enable_tiling=True,
                        tiling_hop_size=timedelta(minutes=1),
                        stream_engine={"spark.sql.shuffle.partitions": "4"})
copy.copy(sfv).enable_tiling   # False
sfv == copy.copy(sfv)          # False (offline differs)

The registry also uses __copy__() to build the version snapshot for no_promote (registry.py:905), so that snapshot is saved without the tiling config.
