feat: move StopTask, CancelPreviousJobs and CleanRepoScheduleTasks to services/actions

This enables all action run state changes (from a not done to a done
state) to also send a notification.

Moved these:

- models/actions/task.go|423 col 6| func StopTask(ctx context.Context, taskID int64, status Status) error {
- models/actions/run.go|190 col 6| func CancelPreviousJobs(ctx context.Context, repoID int64, ref, workflowID string, event webhook_module.HookEventType) error {
- models/actions/schedule.go|122 col 6| func CleanRepoScheduleTasks(ctx context.Context, repo *repo_model.Repository, cancelPreviousJobs bool) error {
