[Feature Request] Support user metadata

[cretz]

Describe the solution you'd like

See https://github.com/temporalio/features/issues/486. Specifically, after https://github.com/temporalio/sdk-go/issues/1673:

• Accept --static-summary and --static-details in all ways to start a workflow (start, signal with start (if present), and scheduled workflows) and populate user metadata with them
• Make sure static summary and static details are shown on workflow describe
• Consider supporting "workflow metadata" query to show current details and defined interactions/handlers (or create separate issue if wanting to handle separately). Unsure if this is wanted on workflow describe/show/whatever or its own command.
• Mark experimental
