Actions support workflow dispatch event (#28163)

fix #23668 

My plan:
* In the `actions.list` method, if workflow is selected and IsAdmin,
check whether the on event contains `workflow_dispatch`. If so, display
a `Run workflow` button to allow the user to manually trigger the run.
* Providing a form that allows users to select target brach or tag, and
these parameters can be configured in yaml
* Simple form validation, `required` input cannot be empty
* Add a route `/actions/run`, and an `actions.Run` method to handle
* Add `WorkflowDispatchPayload` struct to pass the Webhook event payload
to the runner when triggered, this payload carries the `inputs` values
and other fields, doc: [workflow_dispatch
payload](https://docs.github.com/en/webhooks/webhook-events-and-payloads#workflow_dispatch)

Other PRs
* the `Workflow.WorkflowDispatchConfig()` method still return non-nil
when workflow_dispatch is not defined. I submitted a PR
https://gitea.com/gitea/act/pulls/85 to fix it. Still waiting for them
to process.

Behavior should be same with github, but may cause confusion. Here's a
quick reminder.
*
[Doc](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#workflow_dispatch)
Said: This event will `only` trigger a workflow run if the workflow file
is `on the default branch`.
* If the workflow yaml file only exists in a non-default branch, it
cannot be triggered. (It will not even show up in the workflow list)
* If the same workflow yaml file exists in each branch at the same time,
the version of the default branch is used. Even if `Use workflow from`
selects another branch
