[Cosmos] Adds support for non streaming ORDER BY

[simorenoh]

Python follow-up to the .NET PR: https://github.com/Azure/azure-cosmos-dotnet-v3/pull/4362

Using the flag for nonStreamingOrderBy that is now present in the query plan, we choose to create a separate query execution context for these types of operations, draining the results from all the partitions into a priority queue and then returning those results to the user.

This PR includes changes for the following:

• [x] sync client support for dealing with non streaming order by
• [ ] async client support for dealing with non streaming order by
• [ ] samples
• [ ] tests
• [ ] readme
