Backport of new wildcard field type (#53590)
* New wildcard field optimised for wildcard queries (#49993)

Indexes values using size 3 ngrams and also stores the full original as a binary doc value.
Wildcard queries operate by using a cheap approximation query on the ngram field followed up by a more expensive verification query using an automaton on the binary doc values.  Also supports aggregations and sorting.
