x86/fpu: Make the system/cpu init distinction clear in the xstate code as well

Rename existing xstate init functions along the system/cpu init principles:

	fpu__init_system_xstate(): called once per system bootup
	fpu__init_cpu_xstate():    called per CPU onlining

Also make the fpu__init_cpu_xstate() early code invariant:
if xfeatures_mask is not set yet then don't crash but return.
