[NUI][ATSPI] Set AccessibilityHidden for DefaultLinearItem (#3914)

The Seperator of DefaultLinearItem would be not necessary to AT-Client.
This patch is removing Seperator accessible nodes from A11Y tree.

And the Label would be not necessary to AT-Client, if the DefaultLinearItem
provides the Label information.
This patch is removing Label accessible nodes as well.
