Preserve quotedness for Identifier when formatting Query
Cherry-pick of trinodb/trino#80 Presto doesn't maintain the quotedness of an identifier when using SqlQueryFormatter so it results in throwing parsing error when we run prepare query of the syntax [#10739]. This PR solves that above issue. Co-authored-by: praveenkrishna <praveenkrishna@tutanota.com>
