Bug 293703 – [WebDriver] Driver segfault when a pointer move or scroll action is missing a coordinate

• Status: RESOLVED
• Resolution: FIXED
• Component: WebDriver

[Lauro Moura]

`WebDriverService::processPointerMoveAction`/`processWheelAction` need to validate the incoming action request for the required fields before dispatching the actions. If it fails to do so, `Session::performActions` might access the `WebDriver::Action` x and y fields directly without checking whether they're present, leading to errors like `bad_optional_access`.
