Internal QueryParser: Adds Monadic Parser API

Description

Adds a monadic parser API for queries:

    internal static class QueryParser
    {
        public static class Monadic
        {
            public static TryCatch<SqlQuery> Parse(string text);
        }

        public static bool TryParse(string text, out SqlQuery sqlQuery);
        public static SqlQuery Parse(string text);
    }

Instead of adding TryParse to the DOM which is not supposed to have behavior.

Additionally a user can parse the query in an exceptionless manner and still get the error message and full stack trace.

TryCatch<SqlQuery> monadicParse = QueryParser.Monadic.Parse(text);
if(monadicParse.Failed)
{
     handleException(monadicParse.Exception);
}

SqlQuery query = monadicParse.Result;
