[posix] implement virtual time and update tests to utilize virtual time (#2508)

Browse Source 
This commit adds the following features:

- Example posix drivers to support virtual time simulation, allowing tests
  to run faster than real time.

- A python-based simulation driver that coordinates the virtual time
  simulations.  Each alarm event and message transmission across all nodes
  are scheduled in a single discrete time event queue.  As a result, only
  a single node is making forward progress at a time.

- Updated tests to utilize new virtual-time simulator, allowing them to run
  faster than real time.

- To enable virtual time feature, define VIRTUAL_TIME=1 env var and set
  CPPFLAGS=-DOPENTHREAD_POSIX_VIRTUAL_TIME=1.
