[NUI] Propagate AutomationId value to DALi (#4426)

Due to an oversight in #4389, the automationId attribute disappeared from the AT-SPI tree for some Views, causing multiple regressions in Aurum tests. This PR fixes this bug.

The "automationId" key set in AccessibilityAttributes is ignored for controls not backed by a NUIViewAccessible (e.g. BaseComponents, FluxView etc.), because NUIViewAccessible::GetAttributes is never called for such controls. The value of AutomationId should be propagated to dali-toolkit instead, so that is it visible to ControlAccessible::GetAttributes, therefore having an effect for all types of Views (NUIViewAccessible::GetAttributes calls ControlAccessible::GetAttributes first, and then collects any additional attributes stored in View.AccessibilityAttributes).
