After making the service thread task based it is now possible to move the tasks out of `g1ServiceThread.cpp`. The periodic task is moved to its own files and the initialization and registration with the service thread is done while initializing `G1CollectedHeap`.

No functionality is changed for the task, but it has been split up into a header and a source file. 

**Testing**
tier 1-2 + manual testing setting `G1PeriodicGCInterval` through `jcmd`.
