GH-31880: [Python] Table.filter with expression now preserves order with use_threads=True (#34766)

### Rationale for this change

Thanks to https://github.com/apache/arrow/pull/34137, the ExecPlan now has a concept of ordering. When the source node is a Table, the order of the batches in the table is used as the implicit order. And when executing a plan and producing a resulting Table, the default for QueryOptions' `sequence_output` is to honor an order if there is one. 

Given that the `Table.filter` method only consists of a table source node (which adds implicit order) and a filter node (which preserves any ordering), the output will now always be ordered by default, also with the default of `use_threads=True`

### Are these changes tested?

The existing test `test_exec_plan.py::test_filter_table_ordering` still passes.

* Closes: #31880
