Fix leaked value object in NamedPropertySetterCallback()

Fix leaked value object in NamedPropertySetterCallback()

When setting a new value for a V8 object property, the passed along
pointer of CFXJSE_Value is only used, but needs to be released by the
original owner. Use unique_ptr to have the pointer released
automatically.
