[dagit] Track partition set sort order for Launchpad (#8104)

### Summary & Motivation

It's a bit annoying for launchpad users to have to re-sort their partitions every time, if what they want is always a descending order.

Track the sort direction in LocalStorage to reduce this annoyance, keyed by base path, repo address, and partition set name.

### How I Tested These Changes

View a job with a partition set in launchpad. Switch order of partition sort, reload page. Verify that the partition sort order has been preserved.
