perf tools: Pass tool context in the the perf_event_ops functions

Browse Source 
So that we don't need to have that many globals.

Next steps will remove the 'session' pointer, that in most cases is
not needed.

Then we can rename perf_event_ops to 'perf_tool' that better describes
this class hierarchy.
