In process of module testing event_groups.c.

Introduce xPortRunning variable into Win32 simulator port layer.
Add port optimised task selection macro for the GCC Win32 port layer (the MSVC version has had one for a while).
Ensure the event list item value does not get modified by code in tasks.c (priority inheritance, or priority change) when it is in use by the event group implementation.
