tracing: Move graph-time out of function graph options
The option "graph-time" affects the function profiler when it is using the
function graph infrastructure. It has nothing to do with the function
graph tracer itself. The option only affects the global function profiler
and does nothing to the function graph tracer.
Move it out of the function graph tracer options and make it a global
option that is only available at the top level instance.
