Simplify memory management for per isolate data

Simplify memory management for per isolate data

Use smart pointers for FXJS_PerIsolateData owned member variables. Also
move creation and deletion of dynamic object map into
FXJS_PerIsolateData's constructor and destructor. Overall, the
interfaces and memory management should be simpler.
