ES|QL: Add support for match_phrase #125012
Description
tracked in #123043
We want to add support in ES|QL for match_phrase as a separate function in ES|QL:
FROM books
WHERE match_phrase(plot, "Tale of two cities", {"analyzer": "my_analyzer"})
The function will translate to match_phrase query.
The function needs to support all existing options that we have for the match_phrase query.
