lib/event: remove fields from spdk_governor_capabilities

Browse Source 
The spdk_governor_capabilities added lots of capabilities
which went unused, suposedly to mark which callbacks
a governor had implemented.

This made little sense, since capabilities are per core and
not implmenting this APIs made little sense.
With this patch spdk_governor_capabilities is brought in
line with rte_power_core_capabilities.
