context_tracking: Rename context_tracking_is_cpu_enabled() to context_tracking_enabled_this_cpu()

Standardize the naming on top of the context_tracking_enabled_*() base.
Also make it clear we are checking the context tracking state of the
*current* CPU with this function. We'll need to add an API to check that
state on remote CPUs as well, so we must disambiguate the naming.
