Make RowSet iteration and pagination not thread-safe

Description

Currently RowSet supports iterating (and fetching next pages) from multiple threads.

I've initially introduced this feature as a way to support caching and dequeuing rows from different threads.
Looking back, I think its not something we should support and its highly unlikely somebody is using this feature.

Multithreading support adds a lot of complexity to RowSet implementation and makes dequeuing significantly slower compared to simple array / list iterators.

To support multiple consumers, users could rely on BufferBlock<T> or any other queue / data flow library.
