feat(csharp/src/Drivers/Apache): add implementation for AdbcStatement.SetOption on Spark driver

[birschick-bq]

Implement AdbcStatement.SetOption on Spark driver

• "adbc.statement.polltime_milliseconds" -> sets the poll time to check for results to execute a statement.
• "adbc.statement.batch_size" -> sets the maximum size of a single batch to receive.

Making this public seems like the best choice. But if you think it should be private, let me know.

Or maybe made available at the SparkStatement level?

What if we establish a convention of having a static class in appropriate places, like

class HiveServer2Statement : AdbcStatement {
    public static class Options {
        // options common to all HiveServer2-derived drivers go here
        public static string PollTimeMilliseconds = "...";
    }
}

class SparkStatement : HiveServer2Statement {
    new public static class Options : HiveServer2Statement.Options {
        // options specific to Spark go here
        // ...
    }
}

Should these tests roundtrip and verify the option is set correctly?
