Make sure that Actions.perform is always passed a list

[LanWei22]

Fixes #14343
When calling action_sequence.send_actions, we should pass a list not dictionary, so Actions.perform will get a list.

You need to move base.py to the right address (tools/wptrunner/wptrunner/executors/base.py) to show only the right changes.

While this change fixes the test on Chrome and Safari, it breaks the test on Firefox. The reason is Firefox uses a different executor, tools/wptrunner/wptrunner/executors/executormarionette.py, which expects the actions to be specified in the previous format.

To fix the test on Chrome without breaking Firefox, I think the right place is in tools/wptrunner/wptrunner/executors/executorwebdriver.py:

class WebDriverActionSequenceProtocolPart(ActionSequenceProtocolPart):
    ...
    def send_actions(self, actions):
        self.webdriver.actions.perform(actions['actions'])
