Add rerun option for workflows

[ahmedhamidawan]

Fixes #11340

rerun_workflows.mp4

TODO:

• Add tests ❗
• Ensure we can still route to usegalaxy.org/?workflow_id (since I removed that in eb9386a)
• Highlight cases where original inputs can not be set (e.g.: datasets now deleted); maybe we put a dismissible error message on those inputs
• more things...

How to test the changes?

Additional Enhancement:

Inform user when the original rerun values are changed:

We compare the requestState and the current values to tell whether the values are different from the original run at a given point. This check can be disabled.

Additional example case is if a dataset that was formerly used in an invocation, is now deleted, and therefore on landing on the rerun, is not set as the input.
