sched/vtime: Rename vtime_accounting_cpu_enabled() to vtime_accounting_enabled_this_cpu()

Standardize the naming on top of the vtime_accounting_enabled_*() base.
Also make it clear we are checking the vtime 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.
