LibJS: Update Object::define_accessor() to take both getter and setter

Browse source 
This replaces the current 'function plus boolean indicating the type'
API, which makes it easier to set both getter and setter at once.
This was already possible before but required two calls of this
function, which wasn't intuitive:

    define_accessor(name, getter, true, ...);
    define_accessor(name, setter, false, ...);

Which now becomes:

    define_accessor(name, getter, setter, ...);
