Not all features work on ip fields

[jpountz]

Since we switched to points to index ip addresses, a couple things are not working anymore:

• range queries only support inclusive bounds (Add back range support to ip fields. #17777)
• range aggregations do not work anymore (Add back support for ip range aggregations. #17859)
• sorting on ip addresses fails since it tries to write binary bytes as an utf8 string when rendering sort values (Allow binary sort values. #17959)
• sorting and aggregations across old and new indices do not work since the coordinating node gets longs from some shards and binary values from other shards and does not know how to reconcile them (Make ip fields backward-compatible at query time. #18593)
• terms aggregations return binary keys (Fix xcontent rendering of ip terms aggs. #18003)
