x86/fpu: Move the fpstate_xstate_init_size() call into fpu__init_system()

The fpstate_xstate_init_size() function sets up a basic xstate_size, called
during fpu__detect() currently.

Its real dependency is to be called before fpu__init_system_xstate().

So move the function call site into fpu__init_system(), to right before the
fpu__init_system_xstate() call.

Also add a once-per-boot flag to fpstate_xstate_init_size(), we'll remove
this quirk later once we've cleaned up the init dependencies.

This moves the two related functions closer to each other and makes them
both part of the _init_system() functionality.

Currently we do the fpstate_xstate_init_size()
