cc3200: Start the simplelink spawn task using the static task creator.

In VStartSimpleLinkSpawnTask we change xTaskCreate to xTaskCreateStatic
so that the task is created using statically allocated memory for the TCB
and stack.

This means that xTaskCreate function is no longer needed (the static
version is now used exclusively).
