Add support for the "contains" function pushdown for Mongodb

[ZhangJianAo]

When using Trino with the Mongodb, when filtering on most primitive type fields can pushdown to mongo and has good performance. However, filtering on the array field will lead to a table scan and poor performance.
I am working on an improvement to pushdown the "contains" function to MongoDB. So when SQL has conditions like WHERE contains(colArray, -1), trino can pushdown to mongo using {"colArray": -1} to filter documents.
