ES|QL: Add support for match_phrase

[ioanatia]

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.
