HPCC-19842 Declare ISecProperty::setValue

Add setValue to the ISecProperty interface. This eliminates the
need to cast to a concrete implementation in order to set a
member, the existence of which is implied by the declared
getValue method.

HPCC-19842 Add override keyword to setValue implementations
