Implement Task node support

[lvcabral]

Implemented the support for executing a Task as a Worker thread, reusing the Payload and running another instance of the Interpreter. Some limitations are still in place:

• Only 10 tasks supported (until proper performance tests are done)
• The m and m.global are snapshots, not sharing updates with Main thread
• In the task init you can only observe using a single roMessagePort object.
• Not all BrightScript objects, created during init and stored at m can be transferred.
• The memory file system (tmp:, cachefs:) are not shared among threads.
