context_tracking: Rename context_tracking_active() to context_tracking_cpu_is_enabled()
We currently have a confusing couple of API naming with the existing
context_tracking_active() and context_tracking_is_enabled().
Lets keep the latter one, context_tracking_is_enabled(), for global
context tracking state check and use context_tracking_cpu_is_enabled()
for local state check.
