lib/event: Rename context switch monitoring APIs to be concise

spdk_reactor_enable_framework_monitor_context_switch and
spdk_reactor_framework_monitor_context_switch_enabled had been
a little long and not easy to get the meaning.

spdk_framework_enable_context_switch_monitor and
spdk_framework_context_switch_monitor_enabled will be a little
more concise, and hence change the names accordingly.
