What has been deprecated is enabling filtering support using the
'filter_ctrl' APIs [1], now same filtering features can be implemented
using rte_flow APIs and this is the preferred way for DPDK.

Since those filtering features can be enabled via rte_flow too, better
to keep them in the feature list, and mark them enabled for the PMDs
that enabled features via rte_flow API.
That is why PMD feature announcements not added back, they can announce
the feature again when 'filter_ctrl' implementation replaced with
'rte_flow" ones.

Also filter definitions should be clarified more in the features
documentation so that all PMDs can easily figure out to announce or
not these filtering features, also users can understand better what to
expect from this feature.

Fixes: 030febb6642c ("doc: remove deprecated ethdev features")
Cc: stable@dpdk.org

[1]
rte_eth_dev_filter_ctrl()
rte_eth_dev_filter_supported()
These APIs were passing using input related to the filtering by
'filter_type' and type specific structs.
