[osm] adding new validity check to venue names so if the Jaccard(name tokens, street & house numer tokens) == 1 and the address does not have a known venue type e.g. a restaurant, the "venue name" is actually just the street address and can be discarded

The definition of "what is a venue" is pretty loose in libpostal, but
there are several cases we want to avoid:
Firstly, if the venue name is the same as the house number, usually in the
case of a named building, it's not valid.
Sometimes a particular street is synonymous with a tourist attraction or neighborhood
or historic district and OSM might label it as something like a landmark,
which passes the "named place" test but is really just a street, so if the
name of the place is exactly equal to the street name and there's no house number
(this still allows for bars or restaurants, etc. that might be named after the
street they're on), call it invalid.
Often the name or a building in OSM will just be its street address. Example:
addr:housename="123 Park Place"
addr:housenumber="123"
addr:street="Park Place"
This method will invalidate the venue name if and only if
the set of unique tokens in the venue name is exactly equal
to the set of unique tokens in the house number + street name.
This does not apply to known venue typess (like a restaurant)
where we'd want to preserve the name.
