[Tizen][ATSPI] Adds support for enumeration in Property::Value

Property::Value can now be initialized with enumeration value. It will
be converted into int. Similarly user can retrieve int value as
enumeration. Note, that no attempt is made to check, if enumeration
types for setting and retrieving match - user can set with one
enumeration type and retrieve with another.
