Add support for accessibilityItemType prop

[vineethkuttan]

This prop identifies the ItemType property, which is a text string describing the type of the automation element.
ItemType is used to obtain information about items in a list, tree view, or data grid. For example, an item in a file directory view might be a "Document File" or a "Folder".
When ItemType is supported, the string must match the application UI language or the operating system default UI language.

UIA Agent uses this to function access get the prop UIA_ItemTypePropertyId
