Add SORT and DeepSORT tracker workflow blocks

[yeldarby]

Summary

NOTE: Do not merge this until the next version of Trackers is released. It's developed against their @main branch & PyPi won't let us link to a GitHub commit in our requirements. (Marked as non-draft to ensure CI passes.) We also need to add support for using other reid models via Inference.

• add SORT and DeepSORT tracker blocks with UI manifests
• update requirements for trackers 2.0.1
• implement base tracker cache fixes
• add unit tests for trackers
• pin trackers to 2.0.1 to avoid upcoming API change

Closing because we need to wait until we add custom embedding models to the platform. Will reopen when we get there.
