sfc: Generalise filter spec initialisation
Move search_depth arrays into per-table state.
Define initialisation function efx_filter_init_rx() which sets
everything apart from the match fields.
Define efx_filter_set_{ipv4_local,ipv4_full,eth_local}() to set the
match fields. This allows some simplification of callers and later
support for additional protocols and more flexible matching using
multiple calls to these functions.
