Migrate ordered single aggregation path.

For the background of the refactor, see EPIC issue for details

For the overview of the refactored path, see comments at the top of datafusion/physical-plan/src/aggregates/ordered_single_stream.rs

What changes are included in this PR?

• datafusion/physical-plan/src/aggregates/mod.rs: physical planning changes that route the applicable execution to the 'ordered-single-aggregate` path
• datafusion/physical-plan/src/aggregates/ordered_single_stream.rs: main implementation. Overview is at the comments for OrderedSingleAggregateStream, and the entry point for execution state machine is at poll_next()

[2010YOUY01]

This step is mostly similar to the spilling paths of other aggregation modes. We should extract the common logic later.

[2010YOUY01]

here is the key change for this file, just a clean-up to make it easier to be reused by different aggregation modes.
